A power station uses oil-fired boilers which are supplied with fuel from 4 cylindrical tanks, each with 12 m diameter and 11 m high. The calorific value of the oil is 38,039 kJ/kg and its relative density is 0.78. The output from the power station is 77 MW. Assuming the only 21% of the heat input is converted to into electrical energy output, how long will the boilers run (in days) on the oil in the tanks. Correct Answer: 4.7 ± 0.1
