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.
