Constants I Periodic Table You are assigned the design of a cylindrical, pressurized water tank for a future colony on Mars, where the acceleration due to gravity is 3.71 m/s². The pressure at the surface of the water will be 130 kPa , and the depth of the water will be 13.8 m . The pressure of the air outside the tank, which is elevated above the ground, will be 86.0 kPa. Part A Find the net downward force on the tank's flat bottom, of area 2.50 m² , exerted by the water and air inside the tank and the air outside the tank. Assume that the density of water is 1.00 g/cm³.
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.
