1. The problem statement, all variables and given/known data A steam driven turbine generates 200 MW of mechanical power at tan eficiency of 32%. The temperature of the steam at the input is 500 C, and at the output it is 200C a: How much power is input as heat to run this turbine? b: How much power is lost in hear to the environment? c: What is the max ifficiency of any system used to do work with these input and output temps? d: If the waste hear is used to to evaporate water, how many kilograms of water can be evaporated in one hour? 2. Relevant equations a: Qh = work/efficiency = 625MW b: Qh - Work = 425MW c: carnot engine: 1-(Tc/Th) = 1-(473/773) = .338 d: Not sure: Q = mc(delta T) 3. The attempt at a solution As you can see a, b, and c are figured out. I'm not sure how to approach d. No temp is given for the water, so I can't get delta T.
