If the hydrostatic equation is integrated from the Earth's surface to the top of the atmosphere, the resulting equation states that the force on 1 m3 of the Earth's surface is equal to the total weight of the air in a column, which is 1 m2 and as high as the atmosphere. If sea-level pressure is 101,325 N/m2 and the area of the Earth's surface is 5.09 x 1014 m2, then what is the total weight and mass of the Earth's atmosphere?
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.
