A power plant produces 1000 MW of electricity and uses residential oil as the fuel. The oil has a heating value, the maximum energy liberated in combustion, of 43 000 kJ/kg. The overall efficiency of the power plant is 52%. Determine the instantaneous heat input, the daily fuel consumption, and the dimensions of a cylindrical storage tank (L =D) to hold a 3-day supply of oil. The density of the oil is 990 kg/m3. Determine in addition the amount of heat rejected to the environment.
