Question

Oil is used in a steam boiler heating system. Thecombustion of 1.0 lb of oil provides 2.4 x 10 ^7 J. How many kg of oil are needed to provide steam from 150 kg ofwater at 100 degrees C. I do not even know where to begin. Can you please showme the steps to solving this. The answer is 6.4 kg of oil Oil is used in a steam boiler heating system.

Explanation / Answer

enthalpy of vaporization: 2260 kJ/kg 150 kg water *(2260 kJ/kg water) *(1000 J/1kJ)*(1.0 lb oil/2.4e7 J)*(0.454 kg/1lb) = 6.41 kg oil
