Overview
Hydrostatic pressure is the pressure exerted by a fluid at equilibrium at a given point within the fluid, due to the force of gravity. It increases linearly with depth.

Pro Tips
Commonly, gravity (g) is assumed to be 9.80665 m/s².
Total pressure includes the weight of the air above the fluid (Atmospheric Pressure).
Dense fluids like mercury exert much higher pressure than water at the same depth.

Fun Facts
"At the bottom of the Mariana Trench (11 km deep), the pressure is over 1000 times atmospheric pressure."
"Human lungs would be crushed by the pressure if not for special equipment or gas mixtures in deep diving."
"Hydrostatic pressure is the reason why your ears 'pop' when you dive to the bottom of a pool."
