Web26 mei 2024 · Head is the height to which a pump can raise water straight up. Water creates pressure or resistance, at predictable rates, so we can calculate head as the differential pressure that a pump has to overcome in order to raise the water. Common units are feet of head and pounds per square inch. WebPV γ = constant. Let subscripts 1 and 2 stand for inlet and outlet process conditions of the compressor. Then the pressure ratio of the compressor is P 2 /P 1. P 2 /P 1 = (V 1 /V 2) n ... Polytropic compression. P 2 /P 1 = (V 1 /V 2) γ ... Adiabatic compression. The head developed by the compressor is expressed in following compressor equations.
