Fluid+Pressure

What is Fluid Pressure?
Fluid pressure is the pressure at some point within a fluid, such as water or air("Fluid Pressure"). · Pressure is the force per unit area on a surface. o A newton is not a unit of pressure…it is a unit of force. o A pascal is a unit of pressure. o N/m2 and Pa are unit of pressure o Fluid pressure results from the motion of the atoms or molecules that make up the fluid. o Pressure is equal to force divided by area, or P = F/A. · Fluid pressure results from the motion of the atoms or molecules that make up the fluid. · Pressure at a given level in a fluid is the same in all directions. Air pressure increases as elevation increases. o The higher you go up a tall mountain, the less air pressure there is. o At higher elevations, air pressure is less because there is less air above. o Air pressure, or atmospheric pressure, is the pressure exerted by the gas in the Earth’s atmosphere. o Water pressure increases as you go deeper and deeper.

Fluid Pressure occurs when you have a container filled with a fluid. If an object has punctures the container, then the fluid pores out. If it has more then one hole, then the lowest hole or the hole that is closet to the bottom will have a stream going the fearthest. That is because the fluid pressure is more greater towards the bottom. Fluid pressure occurs in one of two situations: Still dont understand? [|Click Here!]
 * 1) an open condition, such as the ocean, a swimming pool, or the atmosphere; or
 * 2) a closed condition, such as a water line or a gas line("Fluid Pressure").

The experiment shown here is a milk jug with three holes drilled in the side. When you fill the jug with of liquid, water will shoot out based on the water pressure (P=density* gravity* height). The stream that shoots the farthest is the bottom hole where the pressure is the greatest.

Key Terms · Pressure – The force exerted on a surface divided by the total area over which the force is exerted. P = F/A · Pascal – A unit of pressure equal to one Newton per square meter or N/m2 · Fluid – A substance that can easily change shape. Water is a fluid, air is a fluid, gas is a fluid, and even glass is a fluid.
