A 250. MW coal-fired power plant burns fuel with an energy density of 35.0 MJ kg-1. Water enters the temp reduction tower at 293 K and leaves at 350. K at a rate of 4200. kg s-1.
4. Calculate the energy removed by the water each second.
5. Calculate the energy produced by the combustion of coal each second.
6. Calculate the overall efficiency of the power plant.
7. Calculate the mass of coal burned each second.
