A Carnot power cycle has a high temperature of 1500 K and a low temperature of 500 K. The pressure at the bottom right of the cycle on a TS diagram (state 3) is 200 kPa and 600 kPa at the bottom left (state 4). The fluid inside is air and can be treated as an ideal gas (cp = 1.005 kJ/kg). Determine a. The pressure at the beginning (state 1) and end of the isothermal expansion (state 2), each in kPa. b. The heat transfer and work, in kJ/kg for each process. c. The thermal efficiency.

A Carnot power cycle has a high temperature of 1500 K and a low temperature of 500 K.
The pressure at the bottom right of the cycle on a TS diagram (state 3) is 200 kPa and 600
kPa at the bottom left (state 4). The fluid inside is air and can be treated as an ideal gas (cp =
1.005 kJ/kg). Determine
a. The pressure at the beginning (state 1) and end of the isothermal expansion
(state 2), each in kPa.
b. The heat transfer and work, in kJ/kg for each process.
c. The thermal efficiency.
