What is the force of air pushing down on us?
The force of air pushing down on us is due to atmospheric pressure. At sea level, this pressure is about 14.7 pounds per square inch (psi). This pressure decreases with increasing altitude.
What is the force of the atmosphere pushing down on us?
The force of the atmosphere pushing down on us is called atmospheric pressure. This pressure is caused by the weight of the air above us pressing down on the Earth's surface. On average, the atmospheric pressure at sea level is about 14.7 pounds per square inch (psi).
What is the measure of the force with which air molecules are pushing on earth surface?
Air Pressure
What is the pressure of 5 meter depth under water?
The pressure at a depth of 5 meters under water is approximately 0.5 atmospheres, which is equivalent to 49 kilopascals. This pressure is caused by the weight of the water above pushing down on the water at that depth.
How much does a pressure treated 6 by 6 weigh per foot?
A pressure treated 6x6 usually weighs around 3.2 pounds per linear foot.
What amount of pounds of pressure is pushing against a persons body at all time?
15 pounds of air pressure are pushing against every square inch of your body at all times.
What are you measuring when you are measuring pressure?
When you are measuring air pressure, you are measuring the force that the air is exerting outwards, on whatever you are using to compress it (since materials resist being compressed). For example, measuring the air pressure in a balloon is measuring the amount of force that the air is pushing against the material of the balloon. This is usually expresed in Pounds per Square Inch (PSI).

Pressure exerted by the air around us is called?
14.69 pounds per square inch (psi). 2,115.36 pounds per square foot. 19,038.24 pounds per square yard. 58,972,852,224 pounds per square mile. If you want to calculate the complete gravitational force of Earth, find the area (in square miles) and multiply it by 58,972,852,224. That will give you, in pounds, the complete gravitational force of Earth.

Why do objects placed in fluids experience a buoyant force?
All fluids exert pressure on the surface of any object in that fluid, but the pressure is not uniform over the surface of the object. Parts of the object that are deeper in the fluid will have more pressure from the fluid pressing against them than parts that are shallower. The amount of the object's surface that is being pressed down by fluid above it will be equal to the amount of surface being pressed up, but the pressure per unit area pressing up will be greater, on average, than the pressure that is pressing down.A 1 square inch column of salt water 1 foot tall weighs just under 0.45 pounds, so it exerts a pressure of (about) 0.45 PSI. That pressure will be in addition to the pressure of any fluid that is pressing down on the top of the water column, such as the atmosphere. Thus the pressure on the surface of the ocean is about 14.7 PSI and the pressure at a depth of 1 foot is about 14.7 + 0.45, or 15.15 PSI.If a cubic object 1 foot on each side was placed in the water with its top right at the surface the top of the cube would have 14.7 PSI * 144 square inches, or 2116.8 pounds of pressure pushing down on it. The bottom would have 15.15 PSI * 144 square inches, or 2181.6 pounds of pressure pushing up on it. The pressure on each side would equal the pressure on the opposite side, so there would be no net pressure pushing sideways. The difference in pressure pushing up and pressure pushing down would be 64.8 pounds, so there would be a buoyant force of 64.8 pounds pressing the object upward. Since the actual weight of the water column is a little bit less than 0.45 that actual buoyant force would be 64 pounds, which is the weight of 1 cubic foot of water. Thus the object is buoyed up by a force equal to the weight of the fluid it displaces.
How many pounds of pressure does it take to break your knee cap?
This depends on which way you are pushing. Your knee is a hinge joint and is made to flex and extend one way only. Pushing the hinge in the other way can be catastrophic and could be broken from upwards of 30 pounds.
What is The force pushing on a surface divided by the area of that suface?
Pressure. (Note that the force must be perpendicular to the surface.) Pressure can my measured in Pascals (N/m2), psi (pounds/in2), atmospheres, or a few other units.
What is 200 psi?
200 psi is a measurement of pressure. Pounds per square inch is what it stands for. Picture a square in then picture 200 pounds pushing on that (and every other) square inch. 200 psi is fairly high pressure. As an example, a car tire is ususally 32 psi.
The measure of the force with which air molecules are pushing on the Earth's surface?
This force is called atmospheric pressure, the force is measured per unit area because the bigger the area the more molecules hit. It is 14.7 pounds per square inch ("psi")
