Pressure Energy

Calculate the potential of pressure energy in a incompressible fluid.

The pressure energy in an incompressible fluid volume, like a pressurized tank with water, can be expressed as

Δ E = Δp / ρ                                (1)

where

Δ E = potential energy (J/kg, Btu/lb)

Δ p = pressure difference (Pa (N/m2), lb/ft2)

ρ = density of fluid (kg/m3, lb/ft3 )

Example - Pressure Energy in a Water Tank

The pressure in a water tank is 10 bar (106 Pa) . With density of water 1000 kg/m 3 the potential pressure energy can be calculated as

E = (106 Pa) / ( 1000 kg/m >3 )

= 1000 J/kg
