A reheat cycle with two stages of reheating is executed with steam expanding initially from 25 MPa and 600 °C. The two reheater pressures are 4 MPa and 1 MPa, and the steam leaves each reheater at 600 °C. Condensation occurs at 40°C.

For 1 kg/s of steam, what is the engine work in kW?

Question

A reheat cycle with two stages of reheating is executed with steam expanding initially from 25 MPa and 600 °C. The two reheater pressures are 4 MPa and 1 MPa, and the steam leaves each reheater at 600 °C. Condensation occurs at 40°C.

For 1 kg/s of steam, what is the engine work in kW?
