Hello everyone. I'm working those days on my graduation project, and I need a little assistance. I have to choose a compressor that would be driven by diesel engine. The compressor should supply about 1.7 kg air and compress it to 2 atmospheres.


It seems that centrifugal compressor or axial may fit, but I got a constraint that its efficiency will be about 90% or more which is pretty high, and these compressors typical efficiency may reach 80-85%. Compressors that do have such efficiencies are reciprocating compressors, but they are not able to supply the appropriate air flow.
Would be glad to hear any suggestions.
Thanks in advance
Oleg
