FLUID PRESSURE 1. A diving bell is designed to withstand pressure of sea water at a depth of 600 meters. (a) What is the gage pressure at this depth? (b) What is the absolute pressure? (c) What total force acts on a circular glass window 15 cm in diameter if the pressure inside the diving bell is atmospheric? Assume density of seawater is 1030 kg/m3
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.
