Suppose you need to calculate the work required to pump oil in a tank to the surface of the tank. So, let's say there is an oil tank that is an upright cylinder and it is buried so that its circular top is 15 feet beneath ground level. The tank has a radius of 5 feet and is 13 feet high, although the current oil level is only 8 feet deep. Calculate the work required to pump all of the oil to the surface. Note: Oil weighs 50 Ib/ft3

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.
