http://www.cheresour...gal-compressor/ is a thread of Cheresources to explain centrifugal compressor polytropic head. It seems that meaning of mentioned head is work exerted per unit mass of the gas (dimensions M^2/L^2), not meters of fluid as in a pump.
Last Web reference, reported by Ankur in his post, gives a formula for head having dimensions as above.
