A800-mw steam power plant, which is cooled by a nearby river, has a thermal efficiency of 40 percent. determine the rate of heat transfer to the river water. will the actual heat transfer rate be higher or lower than this value? why? (round the final answer to the nearest whole number.)

Rate of heat transfer to river=1200MW

So the actual amount of heat rejected ti the river will be less as there will some heat loss to surrounding and in pipes

Explanation:

In order to find the actual heat transfer rate is lower or higher than its value we will first find the rate of heat transfer to power plant:

From First law of thermodynamics:

Rate of heat transfer to river=heat transfer to power plant-work done

Rate of heat transfer to river=2000-800

Rate of heat transfer to river=1200MW

So the actual amount of heat rejected ti the river will be less as there will some heat loss to surrounding and in pipes.

sorry what a asnns
