electric compressor efficiency

Polytropic Efficiency - an overview | ScienceDirect Topics

If a compressor has five stages, and each stage has the same isentropic efficiency η s, then the overall isentropic compressor efficiency will be lower than η s If, for the same example, we assume that each stage has the same polytropic efficiency η p , then the polytropic efficiency of the entire machine is ,
