Helium gas initially at 2 bar, 200K undergoes a polytropic process, with n=k, to a final pressure of 14 bar. Determine the work and heat transfer for the process, each in kJ per kg of helium. Assume ideal gas behavior.
Ok so I have the following:
P1=200kPa
T1=200K
R_He=2.0769kJ/kg*K
Cp=5.1926
Cv=3.1156
k=Cp/Cv=1.6666
P2=1400kPa
I know that
PV^k=const
My trouble is in finding either the mass or the volume of the helium.
Thanks for any help.
