Two kilograms of air within a piston-cylinder assembly execute a carnot power cycle with maximum and minimum temperatures of 750 k and 300 k respectively. the heat transfer to the air during the isothermal expansion os 60 kj. at the end of the isothermal expansion, the pressure is 600 kpa and the volume is 0.4 m^3. assuming the ideal gas model for the air determine: (a) the thermal efficiency.(b) the pressure and the volume at the beginning of the isothermal expansion, in kpa and m^3 respectively.(c) the work and heat transfer for each of the four processes in kj.(d) sketch the cycle on a p-v coordinates.
