Amass of air occupying a volume of 0.15m^3 at 3.5 bar and 150 °c is allowed [13] to expand isentropically to 1.05 bar. its enthalpy is then raised by 52kj (note the unit) by heating at constant pressure. assuming that all processes occur reversibly, sketch them on a p-v chart and calculate the total work done and the total heat transfer.
