An electrical generating plant operates at a boiler temperature of 229°C and exhausts the unused heat into a nearby river at 18°C.If the generating plant has a power output of 870 megawatts (MW)and if the actual efficiency is 3/4 the theoretical efficiency,how much heat per second must be delivered to the boiler? (0°C = 273 K)

A) 8,279 MW
B) 4,140 MW
C) 2,070 MW
D) 2,760 MW
E) 1,600 MW
