What is the difference between hydrostatic pressure and atmospheric pressure?
is the pressure exerted on a surface by the weight of the atmosphere above it.
The atmospheric pressure at the surface of the earth is approximately 100 kPa.
Hydrostatic pressure is the pressure exerted by a fluid at a given point, due to the weight of the fluid above it.
Hydrostatic pressure increases in proportion to depth below the surface because of the increasing weight of the fluid above it.
A mercury manometer works because the hydrostatic pressure of the mercury column balances the atmospheric pressure exerted on the surface of the mercury.
