Air within a piston-cylinder assembly execute an ideal Carnotpower cycle within maximum and minimum temperatures of 600 K and300 k, respectively. The heat added at the high temperature is 250kJ/kg. The lowest pressure in the cycle is 75 kPa. Assuming theideal gas model for the air (constant cv, cp, k, with the followingproperties: kair = 1.4, cv,air = 0.717 J/g.K, Mair = 28.97 g/mol,Universal Gas Constant 8.314 /( . ) _ R = J mol K ),
(a) Sketch the cycle on a p-V diagram;
(b) Determine the thermal efficiency of the cycle;
(c) Determine the specific volume and pressure after the heatrejection process;
(d) Determine the net work per unit mass of the cycle;
(e) Determine the work per unit mass in each of the adiabaticprocesses.
