1. An industrial company operates a steam power plant with reheat and regeneration. The steam enters a turbine at 115 bar and 550 °C and expands to the condenser at 0.10 bar. Steam leaves the first stage at 30 bar and then reheat at 470 C before entering the second stage turbine. At the second stage turbine a mass is extracted to the open feed water heater at 6 bar. Both section of the turbine (first stage and second stage) has adiabatic efficiency of 93 %. A condensate pump exists between the main condenser and the heater. Another pump lies between the heater and condensate outlet line from the heater (condensed extracted steam) a. Compute the enthalpies at each point b. Compute for the mass extracted from the second stage turbine to the open feed water heater C. Efficiency of the cycle.
