Nitrogen (N2) at 100C and 600 kPa expands in such a way that it can be approximated by a polytropic process with polytropic index n = 1.2. Calculate the work and the heat transfer per kg of N2 if the final pressure is 100 kPa. Draw this expansion process on P- v diagram. For nitrogen, take the gas constant R = 0.297 kJ/(kgK) and cv = 0.745 kJ/(kgK). [Hint: Use the non-flow energy equation, NFE E.].

Nitrogen (N2) at 100C and 600 kPa expands in such a way that it can be approximated

by a polytropic process with polytropic index n = 1.2. Calculate the work and the heat

transfer per kg of N2 if the final pressure is 100 kPa. Draw this expansion process on P-

v diagram. For nitrogen, take the gas constant R = 0.297 kJ/(kgK) and cv = 0.745

kJ/(kgK). [Hint: Use the non-flow energy equation, NFE

E.].
