How local gravity affects hydrostatic pressure In the cases of measuring absolute pressure it is necessary to also measure and subtract the atmospheric pressure to determine the true hydrostatic pressure. Since hydrostatic pressure is the pressure solely generated by a column of liquid, it maybe the case that the pressure measured includes the additional component of atmospheric pressure acting on the liquid surface. How atmospheric pressure affects hydrostatic pressure measurement The formula for calculating the hydrostatic pressure of a column of liquid is: P hyd = h

Both of these quantities need to be known in order to determine the hydrostatic pressure of a particular liquid. The hydrostatic properties of a liquid are not constant and the main factors influencing it are the density of the liquid and the local gravity. The height of a liquid column, of uniform density, is directly proportional to the hydrostatic pressure. Hydrostatic pressure is the pressure that is generated by the weight of liquid above a measurement point, when the liquid is at rest.
