For a diatomic gas (such as, H2, O2and N2), it has 5 as degrees of freedom (3 as translational and 2 as rotational degrees of freedom at room temperature; whereas, except at high temperatures, the vibrational degree of freedom is not involved). Why is CpGreater than Cv? The values i...
Better to use the average of the Cp/Cv between compressor inlet and outlet from Chemcad. For ideal gases, Cp/Cv = k = Cp /(Cp-R), where Cp = kJ/kgmole/degK and R=8.314kJ/kgmole/degK. In many cases, the ideal gas value for k is far from the real gas k. Upvote 0 Downvot...
For an adiabatic process involving an ideal gas, the relationship between pressure and volume is given by: PVγ=constant where γ=CpCv. Step 3: Rewrite the adiabatic conditionWe can express this relationship in terms of pressure p: p=kVγ where k is a constant. Step 4: Compare the two ...

For an ideal gas the ratio of specific heats isCpCv=γ. The gas undergoes a polytropic process PV^(n) = a constant. Find the values of n for which the temperature of the gas increases when it rejects heat to the surrounding.
