Heat Exchangers

Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.

Heat Exchanger

The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.

This is Problem 13 of Chapter 3 in Sustainable Energy by Richard Dunlap, 2nd Edition. I need help solving it: A coal-fired generating station has an efficiency of 38% and produces an average electrical output of 1000 MWe.(a) How much coal does it burn per second (kg/s)? Assume the coal is bituminous.(b) How much heat (in joules) is released to the environment per second?(c) How many liters of water at 20°C could the heat in part (b) boil (at STP) per second? For c, here is my idea: use Q = mc(change in T). Here change in T is (100 C - 20 C) or 80 C and c = 4200 J/(kg C) so I can solve for m. Question: I need the density of water to find liters, but density changes with temperature. So, do I use the regular 1000 kg/m^3 or something else?
