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.

Basic steps to compressor unit calculation and selection

Compressor capacity is volume of compressed air flow upon a particular given time and is expressed in m 3 /hour or l/min. Various compressor types vary in capacity to specify particular application of compressor equipment. Amount of inlet air consumed upon a particular given time prior to compression is also considered a unit capacity.
