A fluid can be considered incompressible if it takes a large amount of pressure to compress the fluid. Liquids can be considered incompressible fluids. To determine the hydrostatic pressure of an incompressible fluid refer to equation 1.

**(Eq 1) **$P_1=γh+P_2$

P_{2} = Hydrostatic Pressure

γ = Specific Weight

h = Fluid Head

P_{1} = Initial Pressure
