Isentropic exponent and specific heat ratio
Isentropic exponent and specific heat ratio
(OP)
Hi all,
That's a small question but really make me confused in the control valve calculation.
Could "isentropic exponent" be treated same as "specific heat ratio" in control vavle calculation?
Thanks

RE: Isentropic exponent and specific heat ratio
I suspect that you are talking about the "isentropic expansion factor" which is a synonym for "specific heat ratio" ... in other words, they are the same thing.

Thank you for your reply. Now, I got the idea that for the ideal gas, they are same thing,right?

Note that for pv=RT, the difference of specific heats is easily shown to be, Cp - Cv =R
