A steam power plant is based on the Rankine cycle with reheat (refer to the figure below). Steam is produced by the boiler/superheater (H-1) at 100 bar and 600 C at a rate of 2.5 kgs-1. This is expanded to 10 bar in the turbine T-1 and then reheated to 600 C in heater H-2. The steam is then expanded in turbine T-2 to a pressure of 0.1 bar. The steam is then condensed in condenser (C-1) which operates at 0.1 bar. The liquid water leaving the condenser may be assumed to be saturated. The condensate is returned, via pump P-1, to the boiler as feed. Turbines T-1 and T-2 have 90% efficiencies. The power required for pump P-1 may be assumed to be negligible. Calculate i) the power (kW) produced in each turbine (T-1, T-2) ii) the duty (kJhr-1) of each heater (H-1, H-2) iii) the duty (kJhr-1) of the condenser (C-1), and iv) the thermal cycle efficiency. Is the steam leaving turbine T-2 wet or dry? Note: The enthalpy of saturated liquid water at 0.1 bar is 191.81 kJkg-1
