.A coal-burning factory produces 1225MW of electricity per day and runs at 35%efficiency(η). Determine how much water will be needed daily to cool down the hot steam fromthe combustionin order to runthe plant if the water comes from a nearby Lake and has aaverage temperatureof 150C,5% of the emitted heatfrom the combustionis lost to thesurroundings(i. e., heating up the pipes and energy of the exhaust gas in the stack),and thewater is i) evaporated in a cooling tower or ii) recycled and returnedto the lake at 350C. Forcoal: cp= 2kJ/kg/°C; cv= 1.75kJ/kg/°C;heat released by combustion, or ΔH = 5kW/kg.1Watt = 1J/s
