Extracted text: QI/ Air is compressed from an initial state of 1 bar, 25 oC and the volume of air is 0.0247 m3/kg to a final state of 5 bar , 25 oC and the volume of air is 0.00495 m3/kg. By two different mechanically reversible processes in a closed system, as the following heating at constant volume followed by cooling at constant pressure. Assume air to be an ideal gas with the constant heat capacity, CV= 0.717 kJ/kgK , Cp= 1.005 kJ/kgK, R=0.287 kJ/kgK and y=1.4. Calculate the work required, heat transferred, and the changes in internal energy and enthalpy of air each process and for the entire cycle?
