Propane is to be adiabatically and reversibly compressed in a steady-flow device from 750 kPa and 177°C to 7000 kPa. Calculate the specific work required for this compression treating the propane as an ideal gas with temperature variable specific heats and using the departure charts.
From the ideal gas properties table,
Molecular weight of propane,
From ideal gas specific heat of various gases table,
Calculate the final temperature,
The change in entropy between two states is defined as,
Substitute the value in above entropy relation,
