Question

Find pressure at the bottom of a lake of depth 100m

Answer 1

Hydrostatic pressure at any height below the water surface is calculated by P=hdg where h is the height below the open water surface, d is the density of water and g is the acceleration due to gravity. So if you want to calculate gauge pressure at height h then use formula P=hdg+P∘ where P∘ is atmospheric pressure.

Answer 2

Answer:

you can find the answer using a formulae p = hdg p°

here , p = pressure

h = height

d = density of water

g = acceleration due to gravity

p° = atmospheric pressure
