3.2 In the steam power plant, the turbine receives 700 kg/s of main (live steam at (i) 250 bars and 560°C, (ii) 250 bars and 600°C, (iii) 300 bars and 600°C. The condenser pressure is 0.04 bar. The turbine isentropic efficiency is 0.92. The work of the feedwater pump may be ignored. Calculate: (a) the plant net power output, (b) the plant thermal eff- ciency, and (c) the plant net heat rate.
