Three kg of air at 150 kPa and 77°C temperature at state 1 is
compressed polytropically to state 2 at pressure 750 kPa, index of
compression being 1.2. It is then cooled to the original
temperature by a constant pressure process to state 3. Find the net
work done. (Show the processes on the P-V diagram). [Take Rair
=0.287 kJ/kg K]
