Steam at 100bar, 600°C is received by a Rankine engine and exhaust at 2 bar; The change in potential and kinetic energies are negligible. (a) For the ideal engine find the net work, thermal efficiency, steam rate (the mass of steam used to perform a unit of work), and mean effective pressure. (b) For the actual engine, the brake efficiency is 84%, generator efficiency is 90% and the driven generator produces 30MW. Find the combined work and combined heat rate.

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J). It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).
