Concept explainers

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.

Tire gauges for air pressure as well as most other gauges used in an industrial environment take into account the pressure due to atmosphere on earth that's why your car gauge reads zero before you put it in on your tire to check your pressure this is called gauge pressure. The real pressure with any tire or after or other objects containing pressurized stuff would be a combination of what the gauge reads as well as the atmospheric pressure.
