A 250 MW (electricity) coal-fired power station burns coal with an energy density of 35M J/kg. This power station uses a coolant liquid which enters the cooling tower at a temperature of 68℉ and leaves at a temperature of 170.6 ℉ and flows through the cooling tower at the rate of 3716.8 L/s. The density of the coolant liquid is 1.11 g/mL and its specific heat capacity is 4599.5 J/Kg. K. (a) Calculate the energy removed by the coolant liquid each second. (b) Calculate the energy produced (in MW) by the combustion of coal each second. (c) Calculate the overall efficiency of the power station.(d) Calculate the mass of coal burnt each second.(e) If you assume that this coal has an empirical formula C5H4 and the reaction is a complete combustion, what is the volume of air required for this combustion per hour (in gal)? Assume that air contains 20% oxygen. Water_density = 1.429 g/L.
