Steam at 3MPa and 300oC exits a boiler and goes into a high pressure turbine in which it is expanded to 300kPa. The steam is then sent back to the boiler (constant pressure heat exchanger) and reheated to 300oC. In a secondary turbine, the steam is expanded to 10kPa. Assuming that both the turbines are ideal, what is the thermal efficiency of the cycle? Include the contribution of the pump.
