what is hydrostatic pressure
Answers
Answer :
It's the pressure exerted by a stationary liquid.
Answer:
Hydrostatic pressure is defined as
The pressure exerted by a fluid at equilibrium at any point of time due to the force of gravity.
Hydrostatic pressure is proportional to the depth measured from the surface as the weight of the fluid increases when a downward force is applied.
The fluid pressure can be caused by gravity, acceleration or forces when in a closed container. Consider a layer of water from the top of the bottle. There is a pressure exerted by the layer of water acting on the sides of the bottle. As we move down from the top of the bottle to the bottom, the pressure exerted by the top layer on the bottom adds up. This phenomenon is responsible for more pressure at the bottom of the container.
Following is the formula used to calculate the hydrostatic pressure:
p = ρgh
where,
p is the pressure exerted by the liquid in N.m-2, Pa
ρ is the density of the liquid in kg.m-3, slugs.ft-3
g is the acceleration due to gravity taken as 9.81m.s-2
h is the height of the fluid column in m
