The pressure in a liquid at a given depth is called the hydrostatic pressure. This can be calculated using the hydrostatic equation:
P = rho * g * d
, where P is the pressure, rho is the density of the liquid, g is gravity (9.8 m/s^2) and d is the depth (or height) of the liquid.

What is the hydrostatic equation?
The equation is:
dP/dz = – density*gravity
. Written in English, this is the change in pressure with the change in height is equal to the average density of the air times the gravitational constant.
How do you calculate hydrostatic pressure?
Hydrostatic pressure is calculated
from mud weight and true vertical depth
as follows: Hydrostatic pressure, psi = 0.052 x Mud Weight, lbm/gal x True Vertical Depth, ft. (To convert to SI units, 1.0 psi = 6.9 kPa.)
What is hydrostatic equation used for?
This is the hydrostatic equation,
representing balance between the force on a parcel arising from the pressure gradient and that from gravity under the conditions of hydrostatic equilibrium
.
How do you derive a hydrostatic equation?
∂z = −gρ
. This is the hydrostatic equation. The negative sign ensures that the pressure decreases with increasing height. That is, the pressure at height z is equal to the weight of the air in the vertical column of unit cross-sectional area lying above that level.
What is hydrostatic pressure in simple words?
Hydrostatic pressure is
the pressure exerted by a fluid at rest due to the force of gravity
. It’s the pressure you feel when you dive to the bottom of a swimming pool. Hydrostatic pressure applies to all fluids, meaning all liquids and gases (a fluid is any substance that can flow and change its shape).
What is an example of hydrostatic pressure?
The weight of the fluid above it exerts static pressure on a given point
. The veins and capillaries in our feet have more pressure inside than the ones in our hearts.
What do you mean by hydrostatic?
:
of or relating to fluids at rest or to the pressures they exert or transmit
— compare hydrokinetic.
What is the unit of hydrostatic pressure?
For convenience the most popular pressure units for measuring hydrostatic pressure are
metres of water and feet of water at 4 deg C (39.2 degF)
with a standard gravity of 9.80665 m/s2. The density of pure water at 4 deg C is very close to 1000 kg/m3 and therefore this has been adopted as the standard density of water.
What creates hydrostatic pressure?
hydrostatic pressure[ hī′drə-stăt′ĭk ]: The pressure exerted by a fluid at equilibrium at a given point within the fluid,
due to the force of gravity
. Hydrostatic pressure increases in proportion to depth measured from the surface because of the increasing weight of fluid exerting downward force from above.
What is hydrostatic stress condition?
In continuum mechanics, hydrostatic stress, also known as volumetric stress, is
a component of stress which contains uniaxial stresses, but not shear stresses
. … It is often used interchangeably with “pressure” and is also known as confining stress, particularly in the field of geomechanics.
What does it mean to say the sun is in a state of hydrostatic equilibrium?
What does it mean when we say that the Sun is in a state of hydrostatic equilibrium?
It remains constant; and inward gravitational forces are balanced by outward pressure.
Why is the hydrostatic balance important?
A hydrostatic balance is a particular balance for weighing substances in water. Hydrostatic balance
allows the discovery of their specific gravities
. This equilibrium is strictly applicable when an ideal fluid is in steady horizontal laminar flow, and when any fluid is at rest or in vertical motion at constant speed.
Is the sun in hydrostatic equilibrium?
It is made entirely of hot gas. Apart from some very tiny changes, the
Sun is neither expanding nor contracting
(it is in hydrostatic equilibrium) and puts out energy at a constant rate.
