Atmospheric pressure, sometimes also calledbarometric pressure, is the pressure within the atmosphere of Earth (or that of another planet). In most circumstances atmospheric pressure is closely approximated by thehydrostatic pressure caused by the weight ofair above the measurement point. Aselevation increases, there is less overlying atmospheric mass, so that atmospheric pressure decreases with increasing elevation. Pressure measures force per unit area, with SI units of Pascals (1 pascal = 1 newton per square metre, 1 N/m2). On average, a column of air with a cross-sectional area of 1 squarecentimetre (cm2), measured from mean (average) sea level to the top of Earth's atmosphere, has a mass of about 1.03kilogram and exerts a force or "weight" of about 10.1 newtons or 2.37 lbf, resulting in a pressure at sea level of about 10.1 N/cm2 or 101 kN/m2 (101 kilopascals, kPa). A column of air with a cross-sectional area of 1 in2 (6.45 cm2) would have a mass of about 6.65 kg and a weight of about 65.4 N or 14.7 lbf, resulting in a pressure of 10.1 N/cm2 or 14.7 lbf/in2. In the United States, atmospheric pressure near sea level is commonly rounded to 15 lbf/in2, and expressed as "15 psi" (15 pounds per square inch.) https://youtu.be/_0rqRMm_Eew https://youtu.be/Ngz6wFPtKvI https://youtu.be/xUp-X0jAvCc

What is atmospheric pressure and how is it measured?
 
02:41
What is atmospheric pressure and how is it measured? Atmospheric pressure is pressure exerted by the weight of the atmosphere, which is measured at sea level. Atmospheric pressure is measured with an instrument called a "barometer". The barometer was invented by Evangelista Torricelli - an Italian scientist in the early 1600s. A quick video to explain the theory behind atmospheric pressure and how it's measured using the barometer.

Why don't we get crushed by atmospheric pressure? | #aumsum #kids #education #science #learn
 
06:27
Topic: Atmospheric Pressure Why don't we get crushed by atmospheric pressure? Hey. Did you hear that? His ears popped. Is this related to atmospheric pressure? Yes. We know that our earth is surrounded by a layer of air called the atmosphere. The gravitational force of earth constantly pulls this atmosphere towards itself. Due to this, the atmosphere exerts a pressure on the surface of the earth as well as on the objects present on its surface. This pressure exerted by the atmosphere is called the atmospheric pressure. This atmospheric pressure outside our body is balanced by the air pressure present inside our body. When the atmospheric pressure decreases, it becomes less than the air pressure inside us. Now, to balance the pressure inside and outside our ears, the air present inside rushes out. Whereas, when the atmospheric pressure increases, it becomes more than the air pressure inside us. So, to balance the pressure inside and outside our ears, the outside air rushes in. This movement of air results in that sudden pop. Have you noticed this before? Has your water bottle ever got crushed once your airplane landed? This happens because of changes in the atmospheric pressure. Generally, the atmospheric pressure in the bottle is equal to that on the surface of the earth. Whereas, in an airplane the atmospheric pressure is low as compared to that on the surface of the earth. During the flight, when you open the bottle and drink some water in the airplane, the atmospheric pressure in the bottle becomes low. This is because the low pressure air present in the airplane occupies the place of water which you just drank. However, when the airplane lands and you come out of the plane, the pressure outside the bottle, that is, the atmospheric pressure on the surface of earth is high as compared to the pressure inside the bottle. Hence, the outside air exerts a greater pressure on the surface of the bottle than the inside air. As a result, the bottle gets crushed. Wow. How is he able to lift such a heavy car? Are we also powerful enough to handle such a huge amount of pressure? Yes, to some extent we are also carrying a huge amount of pressure. At sea level, the atmospheric pressure is about 14.7 psi. This means that the atmosphere is exerting 14.7 pounds of force on every square inch of our body which is really huge. So, why don't we feel this immense pressure? This is because various parts of our body such as ears, nose, lungs and stomach also contain air which exerts pressure on the atmosphere which is equal to the atmospheric pressure. In this way, the atmospheric pressure and the air pressure present inside our body cancel each other. As a result, we don't get crushed by the atmospheric pressure.

Everyday Science -- Pressure II Segment 9: Atmospheric Pressure
 
02:43
Air pressure at greater elevations is low, and here on the ground it's high. (So at sea level, air pressure is higher than it is at Mount Everest.) We can't feel the high air pressure here because it matches the pressure inside our bodies. We can see pressure demonstrated when we remove air pressure from the inside of a sealed bag: the contents get squeezed by the higher air pressure on the outside. And when an enthusiastic student — with a trained professional on hand — is vaccuum-packed, he can feel the air pressure, too! (Never put a bag on or over someone's head, and do not vacuum-pack a person. The vacuum-pack demonstration that we use is very specifically tailored for safety issues and so Ellis was completely safe.)

Atmospheric pressure drops as altitude increases, making airfoils, like wings and propellers, less efficient. However, atmospheric pressure is also affected by high pressure and low pressure weather systems. This is reflected in the local barometric pressure reading, measured in inches of mercury and also referred to as the altimeter setting. By reference the local altimeter setting and the density altitude chart, you can determine your pressure altitude.

Fishing How to - Understanding Tidal Coefficient, Barometric Pressure & Solunar!
 
12:34
Here is a great fishing how to video that gives insight on tidal coefficient, barometric pressure & solunar phases. Knowledge is power and the more that you know about these things the better you can plan your fishing excursions. I personally utilize the tool or webpage: tides4fishing.com This is a great FREE website that will allow you to do your reconnaissance for planning your next fishing trip. Here is a brief synopsis of what I cover in the video: I discuss tidal coefficients, which tell us the amplitude of the tide. (Difference in high tides and low). It also helps gauge how fast the water will be coming in or going out. Even though coefficients are the same for the entire planet, the amplitude is quite different depending on what region of the world you are in. I also discuss barometric pressure and how the rising and falling effect the fishing. Barometric pressure is defined as the weight or mass of an entire air column on a unit if surface area at sea level. Fish sense pressure changes through their air bladder. The fish that have smaller air bladders such as wahoo, dolphins and kings for example aren’t effected as much as the species with larger air bladders: trout, redfish, tarpon etc… Reason being is because fish that have smaller air bladders have a body density that’s closer to the surrounding water; therefore they can’t sense the change as much. Fish with larger bladders can sense rapid drops in pressure and they can feel it too. When their bladder expands fish become uncomfortable and may move to deeper water, the last thing on their mind is eating at this point. Lastly I discuss the solunar moon phases and their importance when fishing. Using moon tables you can find when the moon is directly underfoot or overhead. The peak feeding times tend to correspond around new and full moons, you also notice healthier tides. Understanding Major and minor moon phases can really increase your odds of catching more fish.

At purple belt, I found myself struggling to pass the guards of equal or higher caliber practitioners. It was Pressure Passing that completely changed not only the way I passed guard, but my effectiveness of passing. These details and "concepts" really helped: 1. ALWAYS HAVE THE FAR-SIDE UNDERHOOK! -This keeps your oppenent flat. 2. BE ON THE BALL OF YOUR FREE LEG WITH HIPS LOW - This allows you to drive pressure forward and post for base 3.

Deep sea physics: Water pressure and the incredible shrinking head
 
00:32
To illustrate the effect of water pressure on air spaces in the deep sea, a styrofoam head was carried by a submarine, from the surface down into the ocean to 3,000 meters (9,840 feet). Water pressure increases with depth, compressing the tiny air pockets in the styrofoam, and causing the head to shrink. At a depth of 3,000 meters, the pressure is 300 times that on the surface, and presses about 4,400 pounds on every square inch of the head. It would feel like having a 4,400-pound adult hippopotamus sitting on your thumb! Because water is less compressible than air, deep-sea animals often have hydrostatic skeletons (skeletons that are supported by fluid pressure) and lack air spaces in their bodies. Deep-diving mammals, such as elephant seals, have adapted to the immense pressure in the deep waters where they hunt, by having collapsible lungs that press out all the air as they are diving down to depths of up to 2,000 meters! Video producer: Linda Kuhnz
Atmospheric pressure - Video Learning - WizScience.com
 
02:09
"Atmospheric pressure" is the pressure exerted by the weight of air in the atmosphere of Earth . In most circumstances atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point. On a given plane, low-pressure areas have less atmospheric mass above their location, whereas high-pressure areas have more atmospheric mass above their location. Likewise, as elevation increases, there is less overlying atmospheric mass, so that atmospheric pressure decreases with increasing elevation. On average, a column of air one square centimeter in cross-section, measured from sea level to the top of the atmosphere, has a mass of about 1.03 kg and weight of about 10.1 N . Atmospheric pressure is sometimes called barometric pressure. The standard atmosphere is a unit of pressure equal to 101325 Pa or 1013.25 hectopascals or millibars. Equivalent to 760 mmHg , 29.92 inHg, 14.696 psi. The mean sea level pressure is the atmospheric pressure at sea level or the station pressure adjusted to sea level assuming that the temperature falls at a lapse rate of 6.5 K per km in the fictive layer of air between the station and sea level. This is the atmospheric pressure normally given in weather reports on radio, television, and newspapers or on the Internet. When barometers in the home are set to match the local weather reports, they measure pressure adjusted to sea level, not the actual local atmospheric pressure.

► TOP 10 Causes Of High Blood Pressure
 
07:22
How I lowered my dad's blood pressure, without drugs or diets ►►http://drsam.co/yt/SeeItYourself ======================================= Top 10 Causes Of High Blood Pressure ======================================= 1. AGE Most people don’t realize that AGE is one of the BIGGEST factors for high blood pressure. I discuss this in my very important article, but what’s important to note is that after the age of 40, 33% of the population has high blood pressure and after the age of 60, over 71% of the population has hypertension! So, if you’re over the age of 40 and have high blood pressure, it may not be your fault. But it IS your responsibility to fix it right away and here is how I lowered my dad’s blood pressure naturally, in just 30 days. 2. GENETICS & FAMILY HISTORY Well, not much can be done here. This is in fact my own problem because I have a family history (on my dad’s side) of hypertension, heart attacks and especially strokes. You can read more about it, include my personal favorite solution that my dad, my family and I use to promote healthy blood pressure levels, naturally! 3. SMOKING Come on people, smoking has NO health benefits. STOP smoking! 4. ALCOHOL A little bit of alcohol is okay, especially if it’s organic red wine. But drinking every night will cause damage to your heart, arteries and liver. Alcohol is a toxic and it’s acidic, both being bad for your body. 5. BEING OVERWEIGHT Similar to smoking, being overweight has no health benefits. And the older you get, the harder it is to lose that unwanted fat. 6. SODIUM Salt has its benefits actually. Regular table salt or salt found in processed foods and packages is BAD for you. However, “natural” salts such as Himalayan rock or Celtic sea salt is GOOD for you and can actually help LOWER blood pressure. I’ll discuss this in a future article. 7. STRESS Well know stress is bad. However, you can’t get rid of it. What’s important is the MEANING you give to stressful situations. If you freak out, get negative and focus on the problem the entire time … you put your body under extra stress. The secret is to focus on the SOLUTION and to know that “this too shall pass” and worrying about the problem isn’t going to help anything… Especially our blood pressure or heart. 8. LACK OF PHYSICAL ACTIVITY We sit too much these days. Just get outside and walk daily, even if it’s just for 15-20 minutes. It’ll do wonders for your physical AND mental health! 9. MEDICAL CONDITIONS This goes back to “genetics”. And if you know you have a genetic “problem”, which is making things worse, then you MUST make changes to your life-style because your body is more sensitive than the average person. This is a similar problem with my dad and why he had a stroke. 10. MEDICATION Ironically, many “heart” medications actually cause more heart PROBLEMS in the long run. They can increase your cholesterol, blood sugar or blood pressure levels. They can decrease blood flow and circulation. And they all cause extra stress on your liver and kidneys, which then cause more problems for your heart.

This animation is created from 8158 images plotting 500 hectopascal geopotential height and sea level pressure for each day from September 1, 1999 to October 31, 2010. The step is 12 hours, so there are two frames per day. Each plot was made by using the new historical archive from meteociel (http://www.meteociel.fr/modeles/archives/archives.php) (data from ncep), performing a "batch" download using an ad-hoc python script made by me.

In this video we will be studying about the different pressure belts on Earth and the different kinds of winds. We will also study the different instruments to measure the atmospheric pressure like the mercury barometer , aneroid barometer, altimeter etc, We will also study the different instruments to measure the wind direction and wind speed which are wind vane and anemometer respectively. There are basically two types of winds: 1. Permanent Winds: Winds which blow throughout the year 2. Local winds: Winds which blow over a smaller area in a particular time Permanent winds include the Trade Winds and Westerlies which blow from the sub tropical high pressure belt to equatorial low pressure belt and sub polar low pressure belt respectively.

Difference Between Low Pressure and High Pressure
 
00:38
High pressure systems circulate clockwise. These "motions" (caused by these circulations) are the building blocks in our atmosphere. They give us our weather. A Low's counter-clockwise circulation forces air upward (ultimately resulting in condensation, cloud formation and ultimately precipitation).There are two physical differences between Low pressure systems and High pressure systems. Secondly, is the atmospheric motion that they cause. These "motions" (caused by these circulations) are the building blocks in our atmosphere. They give us our weather.Adding to Kim Aaron 's answer: in "high pressure" regions, the weather is usually warmer and dryer than the surrounding areas. In "low pressure" regions, the ...The terms high and low pressure systems are common in weather reporting. They are sometimes confusing to tell apart.

This is me freediving down to 75 feet with an empty water bottle into the the Volusia Blue Spring cave / cavern. This shows the great amount of air compression that happens under water. Of course, the bottle also re-inflates when I return to the surface.

Vapor Pressure and Boiling
 
01:54
The molecules leaving a liquid through evaporation create an upward pressure as they collide with air molecules. This upward push is called the vapor pressure. Different substances have different vapor pressures and therefore different boiling points. This is due to differing intermolecular forces between molecules. The vapor pressure of a liquid lowers the amount of pressure exerted on the liquid by the atmosphere. As a result, liquids with high vapor pressures have lower boiling points. Vapor pressure can be increased by heating a liquid and causing more molecules to enter the atmosphere. At the point where the vapor pressure is equal to the atmospheric pressure boiling will begin. In effect, without any external pressure the liquid molecules will be able to spread out and change from a liquid to a gaseous phase. The gas, as bubbles in the liquid, will rise to the surface and be released into the atmosphere.
