A Steam Power Plant Operates On An Ideal Reheat Rankine Cycle Steam At A Rate Of 15kg S Enters The High Pressure Turbin 1 (79.9 KiB) Viewed 45 times

A steam power plant operates on an ideal reheat Rankine cycle. Steam at a rate of 15kg/s enters the high-pressure turbine (HPT) at a pressure and a temperature of 10 MPa and 600°C respectively. The HPT expands the steam to a pressure of 3 MPa. The steam is then reheated at constant pressure of 3 MPa to a temperature of 600°C. In the low-pressure turbine (LPT), the steam is then expanded to a condenser pressure of 15 kPa and leaves the condenser as saturated liquid. Given that the isentropic efficiency of the LPT is 90%. Using the inlet for the pump as state 1, sketch the cycle on a T-s diagram and determine: a) The actual work input by the pump (kJ/kg), b) The temperature at the outlet of the HPT (°C), c) The net power output (kW), and d) The thermal efficiency of the cycle (%).
