Question

A power plant running at 37{\rm \\%} efficiency generates 370MW of electric power.

Part A

At what rate (in MW) is heat energy exhausted to the river that cools the plant?

Answer 1

$Efficiency = \frac{Usefulpower}{Total power} \Rightarrow \frac{37}{100} = \frac{370}{P_{total}}\Rightarrow P_{total} = 1000 MW$

$P_{total}= P_{useful}+P_{to the River} \Rightarrow 1000 MW = 370MW + P_{river}$
$\Rightarrow P_{river}=630 MW$

Answer 2
