Question

Q5. Propane is compressed irreversibly from 5 bar and 323 K to 15 bar and 343 K by an adiabatic, steady-state compressor. For propane, Tc-: 370 K and PC 42.5 bar and Cp *-29.6 J/mol a) Write down the energy balance. b) Calculate the work input per mole of propane, assuming that propane obeys the Clausius equation of state PV-b)-R.T Here, b is the size parameter of the van der Waals eos. For propane Tc-369.9 K and Pc 42.5 bar c) Repeat, assuming that propane obeys the complete van der Waals eos.
