Hydrostatic pressure from density, height and acceleration
==========================================================

Hydrostatic pressure is the pressure exerted by a fluid at equilibrium at a given point
within the fluid, due to the force of gravity.

**Conditions:**

#. The only force acting on the fluid is the gravitational force.
