# HYDROSTATIC PRESSURE CALCULATOR

Pressure in a continuously distributed uniform static fluid varies only with vertical distance and is independent of the shape of the container. The pressure is the same at all points on a given horizontal plane in the fluid. The pressure increases with depth in the fluid. Liquids are so nearly incompressible that we can neglect their density variation in hydrostatics. The pressure p at any depth h below the free surface is given by the equation p=γh+ p0 (or p=ρgh+ p0) where reference pressure p0 would correspond to the pressure acting on the free surface and h is called the pressure head which is interpreted as the height of a column of fluid of specific weight required to give a pressure difference p-p0.
