Lets say your mass is 100 kgs. And lets assume you have the weird ability to stand on a quarter. The quarter has a diameter of 2.5 cm. (100 cm = 1 meter) a) what is the PRESSURE on the quarter in Pa ? b) convert that to psi (6895 Pa = 1 psi)
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.
