You are about to enter the office of your supervisor. you are an intern in a power plant. You forget you had a report on the cooling rate of water supplied to the power plant. Information available Power Plant output 5x10^6 kW Power plant operates between 750F and 120F. Maximum temperture rise in the coolng water is 25F. What is the cooling rate water supplied to the power plant. I submitted this question before. Could it also be solved using the Thermal efficiency? You have operating temps. Assuming Carnot Calculating Qh from thermal efficiency.  Then Qc. Energy transferred to water equal Qh-Qc. Equal cooling rate in watts.
