Atypical coal-fired power plant burns 260 metric tons of coal every hour to generate 2.9×106 mj of electricity. 1 metric ton= 1000 kg; 1 metric ton of coal has a volume of 1.5 m3.the heat of combustion is 28 mj/kg. assume that all heat is transferred from the fuel to the boiler and that all the work done in spinning the turbine is transformed into electrical energy.
suppose the coal is piled up in a 12 m × 8.0 m room. how tall must the pile be to operate the plant for one day?
what is the power plant's thermal efficiency?
