If you dive under water, at what depth you will experience 1 atm of pressure due to the water above you? NOTE: If you start your dive at sea level, the total pressure you will experience is 1 atm plus the pressure due to the water above you. Here I am just asking at what depth the pressure due to the water would be 1 atm (ignoring the pressure due to the atmosphere above the water). Or in other words, at what depth would you experience a total pressure of 2 atm (when accounting for the atmospheric pressure). 10 m 0.1 m 1000 m 100 m
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.
