A steam power plant produces 50MW of net work while burning fuel to produce 150MW of heat energy at the high temperature. Determ
Mazyrski [523]

Nth =\frac{W net, out}{Qh}

50MW is our net output.

Then, we plug it in.

= \frac{50MW}{150MW} = 0.333 or 33.33%

W net, out = Qh - Ql

Ql = Qh - W net,out

Plug the values in.

Then, it becomes:

= 150MW - 50 MW

= 100MW

Thus, the cycle thermal efficiency is 33.33% and the heat rejected is 100MW.
