Air in a pistoncylinder assembly undergoes a Carnot power
Chapter 6, Problem 6.33(choose chapter or problem)
Air in a piston–cylinder assembly undergoes a Carnot power cycle. The isothermal expansion and compression processes occur at 1400 K and 350 K, respectively. The pressures at the beginning and end of the isothermal compression are 100 kPa and 500 kPa, respectively. Assuming the ideal gas model with \(c_{\mathrm{p}}=1.005 \mathrm{\ kJ} / \mathrm{kg} \cdot \mathrm{K}\), determine
(a) the pressures at the beginning and end of the isothermal expansion, each in kPa.
(b) the heat transfer and work, in kJ/kg, for each process.
(c) the thermal efficiency
