1. The problem statement, all variables and given/known data The electric output of a power plant is 750 MW. Cooling water flows through the power plant at the rate 1.0*10^8 L/hr. The cooling water enters the plant at 16 degrees C and exits at 27 degrees C. What is the poer plant's thermal efficiency? 2. Relevant equations W = Qh - Qc n=Wout/Qh 3. The attempt at a solution w=Qh-Qc 790MW=Qh-Qc tried to solve for Qc in order to find Qh but couldn't figur out how to get Qc from 1.0*10^8 L/hr to MW.
