Q3. The steam at 215 bar and 500 °C is supplied to a steam turbine. It expands to 40 bar and 280 °C. It is then reheated to 490 °C and expands to 8 bar and 270 °C. The steam coming out from the second expansion of the turbine is further reheated to 490 °C and expands to condenser pressure of 0.07 bar. The steam entering into the condenser is dry saturated. Assuming the pressure losses in first heater of 1 bar and in second heater 0.5 bar, find (a) the thermal efficiency and power developed if the flow of steam is 10 kg/s (b) the isentropic efficiency of the expansion stages. Neglect the pump work. Mis (42.8 % 1738 kA/ 70 COC
