A typical coal-fired power plant burns 290 metric tons of coalevery hour to generate 730 MW of electricity. 1 metric ton=1000 kg.The density of coal is 1500 kg/m^3 and its heat of combustion is 28MJ/kg. Assume that all heat is transferred from the fuel to theboiler and that all the work done in spinning the turbine istransformed into electrical energy.
a.) Suppose the coal is piled up in a 13.0 m 14.0 m room. How tallmust the pile be to operate the plant for one day? (in m)
b.) What is the power plant's thermal efficiency? (in %)
