2010-3-28  V1 = 3.141593 / 4 * bore * bore * stroke * rpm. For a screw compressor the same procedure applies, but is much more difficult. Only the manufacturer knows the entrapped volume of air per revolution, as the shape of the screws is very complicated. More over the internal compression ratio has to be known as well.

Rotary Screw Compressor Power Calc. Student

2010-3-11  All PD compressors are evaluated on an adiabatic compression cycle. If you see the basic thermodynamic equations for adiabatic compression, density does not play a role in the power calculations. The specific heat ratio (Cp/Cv) however does play a role & is a function of the gas handled.
