A 1000-MW supercritical double-reheat steam power plant operates with the main (live) steam condition of 250 bars and 560°C and the condenser pressure of 0.04 bar. The steam is reheated first at 30 bars to 560°C and then at 4 bars to 560°C. The turbine efficiency is 0.92. The feed pump work may be ignored. Calculate: (a) the plant net specific work, (b) the plant thermal efficiency, (c) the plant steam mass flow rate, and (d) the plant heat rate.

Question
A 1000-MW supercritical double-reheat steam power plant operates with
the main (live) steam condition of 250 bars and 560°C and the condenser
pressure of 0.04 bar. The steam is reheated first at 30 bars to 560°C and
then at 4 bars to 560°C. The turbine efficiency is 0.92. The feed pump
work may be ignored.
Calculate: (a) the plant net specific work, (b) the plant thermal efficiency, (c) the plant steam mass flow rate, and (d) the plant heat rate.
