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.

Question

A hydraulic press has a safety feature which consists of a hydraulic cylinder
with a piston at one end and a safety valve at the other. The cylinder has a
radius of 0.0220 m and the safety valve is simply a 0.00800-m radius
circular opening at one end, sealed with a disk. The disk is held in place by a
spring with a spring constant of 825 N/m that has been compressed
0.0095 m from its natural length. Determine the magnitude of the minimum
force that must be exerted on the piston in order to open the safety valve.
