In a Rankine cycle with reheating, the steam leaves the boiler at 2.5 MPa and 600 ºC and enters the high pressure turbine where it expands to a pressure of 1 MPa to be then subjected to a reheating process from where it leaves at 1 MPa and 600 ° C. The steam at these conditions enters the low pressure turbine and expands up to the condenser pressure of 50 kPa. The heat that is extracted in the condenser is 1500 kJ / s. If the adiabatic efficiency of the turbines and the pump is 95%, determine the total heat flow in kJ / s delivered to the boiler.
