CALCULATION OF POWER FACTOR. P is Power kW Z gas compressibility factor can be defined on an Amagat diagram by calculating the reduced pressure and reduced temperature of the gas P 1 Pressure inlet compressor kPa P 2 Pressure outlet compressor kPa Q m Compressor throughput kgs kGas isentropic coefficient. In AC circuits the power factor is the ratio of the real power that is used to do work and the apparent power that is supplied to the circuit. S kVA 3 V L-LV I A 1000.
