01: 0.5 kg of air executes a Carnot power cycle having a thermal efficiency of 50%. The heat transfer to the air during isothermal expansion is 40 kJ. At the beginning of the isothermal expansion the pressure is 7 bar and the volume is 0.12 m³. Determine the maximum and minimum temperatures for the cycle in Kelvin, the volume at the end of isothermal expansion in m², and the work and heat transfer for each of the four processes in kJ. For air Cp 1.008 kJ/kg. K, Cv= 0.721 kJ/kg. K.
