Air within a piston-cylinder assembly execute an ideal Carnot
power cycle within maximum and minimum temperatures of 600 K and
300 k, respectively. The heat added at the high temperature is 250
kJ/kg. The lowest pressure in the cycle is 75 kPa. Assuming the
ideal gas model for the air (constant cv, cp, k, with the following
properties: kair = 1.4, cv,air = 0.717 J/g.K, Mair = 28.97 g/mol,
Universal Gas Constant 8.314 /( . ) _ R = J...
