Specific heat ratio in gas compression
Specific heat ratio in gas compression
(OP)
In gas compressor; what is the specific heat ration? How could it affect the compressor performance?
in compressor's data sheet; I can see Cp/Cv varying with the temperature. is this the only parameter which could affect it?
thanks

"Although the pertinent formulae for the compressibility factor, the polytropic volume and temperature exponent were published in the 1940s, the message has, even today, not reached all engineering contractors that different exponents for calculating
head and temperature have to replace the traditional "ratio of specific heats", which is irrelevant for real process gases..."
"...But even today the message has not got around to all engineering companies that different exponents for head and temperature replaced the (perfect gas) values K= cp/cv , which have become irrelevant for process gases."
