which one of the following fuels has the highest calorific value?
300186
Natural Gas: Highest calorific value. Calorific Value of a fuel is the amount of energy produced by a unit mass of the fuel on its combustion. Natural Gas is at the top of the table at 13Kcal/g followed by Propane and Butane at 11.9 and 11.8 Kcal/g, respectively. And Gasoline ranks fourth at 11.3Kcal/g.

In the cost of operating private aircraft, jet fuel is usually the largest variable factor. For instance, as we noted in our analysis of the operating costs of the Embraer 300, fuel is the largest variable cost - $1,292 per hour. The pricing per gallon of Jet A fuel can vary significantly, as can the typical burn rate.

In literature the net calorific value of the fuel is obtained by subtracting from higher calorific value the amount 2466 kJ/kg (latent heat of dry and saturated steam at STP (15°C) conditions) (amount of water formed because of the combustion of 1 kg fuel.)

LPG is considered an ideal fuel because of the following reasons: (i) LPG burns with a blue smokeless flame, and leaves no ash behind. ... Therefore, LPG is a clean fuel. (ii) LPG has a high calorific value as compared to other common fuels.

Pure cetane is assigned the highest cetane number, i.e. 100 (most ignitable) and pure 1-methylnaphthalene the lowest cetane number 0 (least ignitable). The cetane number describes the percentage of cetane found in the mixture that corresponds to the ignition quality of the test fuel.
