GAS COMPRESSION FINAL TEMPERATURE

GAS COMPRESSION FINAL TEMPERATURE

GAS COMPRESSION FINAL TEMPERATURE

(OP)
I have asked this question before.
It seems to me that final gas temperatures during compression are based on an isentropic process and an ideal gas (pv=rt and cp/cv =constant
If so, why not consider real gas effects? Also, is there a way to consider efficiency of the compression process?

RE: GAS COMPRESSION FINAL TEMPERATURE

Actually for lower pressures(say, for 10 to 20 bar) there will not be deviation from ideal gas behaviour. Moreover, Isothermal and Adiabatic conditions give you two end limits for the compression process by which you can have some approximation. You do have to incorporate compressibility factors into equations when calculating volumetric efficiency and power consumption but no problems with temperature calculations.

If you give your e-mail id, I can send you a good paper on compression basics(keep your mail box vacant as the file size is 2.3MB)

dear quark,
could you pls forward the same to me also

RE: GAS COMPRESSION FINAL TEMPERATURE

There was some problem uploading the file. I will try sometime after.
