2. The total heating value of liquid propane after vaporization is 35.4 MJ/kg and that of heating oil is 45 MJ/kg. The average prices of heating oil and liquid propane are $3.18 and S2.65 per US gallon respectively (density of heating oil and liquid propane are 3.4 and 2.2 kg/US gallon respectively) but an after burning clean up equipment costing $10,000 that would last for 25 years would be needed for using heating oil as fuel. What type of fuel is preferred if a house needs an average of 60,000 MJ of fuel per month on the average for MARR to be 10% pa?
