Main Question or Discussion Point

Hi everyone!
I have a question and I would be so thankful if you could help me!
For a Centrifugal Gas Compressor, if I have the flow rate, the input and output temperatures and pressures in specified rpm, then could I calculate its needed work, isentropic head and efficiency??? how?
Thanks!
Sara

Given the input values you listed, you should have enough to fix the state at the inlet and output of the compressor. Is this homework?

This page summarizes calculation of required work for an isentropic compressor: http://www.engineeringtoolbox.com/specific-work-turbo-machines-d_629.html
Thanks!
No this isn't a homework actually!
I think the relations in this page is for when the gas is ideal and natural gas doesn't behave such as an ideal gas or at least assuming it as an ideal gas won't lead to the accuracy which I need.
any idea?
Thanks again!
Sara
