I was told before of the 10hp per gallon per hour rule of thumb.
So that a 240hp engine would consume around 24 gallons/hour.
I found out that 1 gallon of gas has about 125,000btus
So this works out to 20% use of the energy in the gas.
80% is wasted.
1 Gallon of Gas = 49.11 hp/hour 100%
1 horsepower (550 ft*lbf/s) is equivalent to: 2,545. btu«IT» per hour
240 hp= 4.9 gallons per hour. 100%
As I said of limited interest but if the amount of energy in the gas could be used instead of dumped then the Hp would go up or the economy would
The gas is used as a coolant
The energy is being rejected by the water cooling
the energy is being dumped out of the exhaust for cooling
$1.50 per gallon means that $1.20 is wasted. 30 cents is used for power production. I think this is a better percent figure.
