Centrifugal Compressor Power Calculation

2017-5-18  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.

Turbocharger Compressor Calculations - GN/TTyPE

2007-12-14  For example, if the compressor is 70% efficient, this means that 70% of the power put into the compressor is used in building air pressure. The other 30% of the power is used heating up the air. That is why we like high efficiency compressors; more of the power is being used on building pressure and less is used heating up the air.
