Two kilograms of air within a piston-cylinder assembly execute an ideal Carnot power cycle within maximum and minimum temperatures of 750 K and 300 k, respectively. The heat transfer to the air during the isothermal expansion is 60 kJ. At the end of the isothermal expansion, the pressure is 600 kPa. Assuming the ideal gas model for the air (cv, cp, and specific heat ratio k, are constants and: kair=1.4, cv,air=0.717J/g.K, Mair =28.97g/mol, ),

(a) Sketch the cycle on a p-V diagram;
(b) Determine the thermal efficiency of the cycle;
(c) Determine the pressure and volume at the beginning of the isothermal expansion;
(d) Determine the work and heat transfer for each of the four processes.
