α 5) The net power output of the turbine in an ideal reheat-regenerative cycle is 100 MW. Steam enters the high-pressure (HP) turbine at 9 MPa, 550°C. After expansion to 0.8 MPa, some of the steam goes to an open feedwater heater and the balance is reheated to 400°C, after which it expands to 10 kPa. The isentropic efficiency for both the turbine and the pump is 85 percent. Determine; (i) (ii) (iii) (iv) (v) 33 Describes the thermodynamics process on T-s diagram and schematic diagram; calculate the steam flow rate to the HP turbine; determine the fraction of steam extracted from the turbine for the open feedwater heater; calculate the thermal efficiency of the plant; if there is a 10°C rise in the temperature of the cooling water, determine the rate of flow of the cooling water in the condenser.
