Unformatted text preview: evaporative cooling towers for a 1000-MW nuclear power plant. The efficiency of the plant is 32 %, and all of the waste heat is assumed to be dissipated through evaporative cooling with no direct heat lost to the atmosphere. The make-up water reduces the temperature of the system by 15 C. 5. Because CE3501 meets very early in the morning, you often set your coffee maker the night before to make 1 L of coffee. This morning you woke up and found that your coffee pot only contained a solid brown mess-all the water evaporated. Luckily, you have a very sophisticated coffee maker, and the readout tells you that the initial water temperature was 60 F and the water vapor was then heated to 300 F. Given the following information, what was the total amount of energy added to the water? Boiling point of water =212 F Lvap-water (from 60 F) = 1016 BTU/Ib Cwater vapor = 10 BTU/(IbF)...
