A 600-MW steam power plant, which is cooled by a nearby river, has a thermal efficiency of 50 percent. Determine the rate of heat transfer to the river water. Will the actual heat transfer rate be higher or lower than this value

600MW

Explanation:

First and foremost, we have to calculate the rate of heat that is supposed to the power plant. This will be:

= 600 / 50%

= 600 / 0.5

= 1200 MW

The rate of heat transfer to the river water will then be:

= 1200 - 600

= 600MW

Therefore, the actual heat transfer rate is thesame as this value as we got 600MW.
