The energy content of ethanol is 76,100 BTU/US gal (5.89 kilowatt-hours per litre), compared to 114,100 BTU/US gal (8.83 kWh/L) for gasoline. (see chart above) A flex-fuel vehicle will experience about 76% of the fuel mileage MPG when using E85 (85% ethanol) products as compared to 100% gasoline.
As of October 2013, the retail cost of propane was approximately $2.37 per gallon, or roughly $25.95 per 1 million BTUs. [58] This means that filling a 500-gallon propane tank, which is what households that use propane as their main source of energy usually require, cost $948 (80% of 500 gallons or 400 gallons), a 7.5% increase on the 2012 ...
b = 0.08445 liter per mole Density of liquid and gas. Propane is highly temperature dependent. [3] ... log of propane vapor pressure. Uses formula: ...
LPG may be used for a supplemental fuel for diesels of all sizes. Diesel contains 128,700 BTU per US gallon, where propane contains 91,690 BTU per US gallon. If LPG is 30–40% less expensive, there may very well be a saving. Any actual savings are dependent on the relative cost of diesel versus LPG.
= energy content per gallon of gasoline = 115,000 Btu/gallon, as set by U.S. DoE and reported by the Alternative Fuel Data Center. [ 14 ] E M = {\displaystyle E_{M}=} wall-to-wheel electrical energy consumed per mile ( Wh /mi) as measured through EPA's five standard drive cycle tests for electric cars and SAE test procedures [ 13 ] [ 39 ]
The painful price per gallon of gas gets all the headlines, but this year's inflation has not been kind to people who rely on propane either. Residential propane prices typically rise in the peak ...
Plus, each of these are usually pretty cheap, which is great since you’ll usually need about 4 gallons of oil for a 12- to 14-pound turkey (usually for propane turkey fryers), Gilbert adds. In ...
Specific energy is energy per unit mass, which is used to describe the chemical energy content of a fuel, expressed in SI units as joule per kilogram (J/kg) or equivalent units. [1] Energy density is the amount of chemical energy per unit volume of the fuel, expressed in SI units as joule per litre (J/L) or equivalent units. [2]
