Compressor power calculation - Centrifugal, rotary ...
1. Formula : compressor power calculation. For 1 compressor stage, the isentropic compression is the following :. P is = 2.31*(k/(k-1))*(T dis-T suct)/M*Q m. A compression is said isentropic when it is carried out by an ideal compressor, without friction, without internal leakage and while being perfectly insulated.
Centrifugal Compressor Power Calculation
To calculate centrifugal compressor power, we need these gas properties: compressibility factor (Z), molecular weight (MW), inlet gas temperature, inlet gas pressure, outlet gas pressure, adiabatic component (Cp/Cv), and mass flow rate. Let’s start with an example while I show you step-by-step of the calculation method.
