In a gallon of gasoline, there is approximately 124,884 btu. BTU refers to British thermal unit. It is actually a traditional unit.
For regular gasoline, 125,000 BTU per US gallon
Yes. Kerosene has 140,000 btu's per gallon and gasoline has less.
Gasoline can generate roughly 20K BTU/lbm. There are 6 lbm per US gallon.
114,000 BTU/gallon
A gallon of gasoline contains about 132x106 joules of energy, which is equivalent to 125,000 BTU or 36,650 watt-hours:
114100 Btu
140,000 btu/gallon, nominal
The BTU (British Thermal Unit) content of gasoline can vary slightly based on formulation and additives, but generally, 87 octane unleaded gasoline contains about 114,000 BTUs per gallon. E10 blends (like 87E10 and 89E10, which contain 10% ethanol) typically have a slightly lower BTU content, around 111,000 BTUs per gallon due to the ethanol. Premium gasoline (91 octane) generally has a similar BTU content to regular unleaded, around 113,000 to 114,000 BTUs per gallon.
BTU is an abbreviation for British Thermal Unit. This represents how much heat or energy is required to increase the temperature of 1 lb of water by 1 degree Fahrenheit. Gasoline, on average, creates between 115,000 and 125,000 BTUs. In contrast, ethanol creates about 75,000 BTUs.
Propylene has a lower heating value of approximately 21,500 BTU per gallon.
The energy content in fuels is often measured in BTU (British Thermal Units). I'm assuming that you're talking about compressed natural gas, as in the form that is used in some cars like the Honda Civic GX. One gallon of compressed natural gas contains 138,700 BTU. One gallon of gasoline contains 125,000 BTU. [http://www.bts.gov/publications/national_transportation_statistics/2002/html/table_04_06.html]
While not as a chart, this is an idea about combustion energy values: Ethanol 77,000 Btu per gallon, Gasoline 125,000 Btu per gallon, Diesel 135,000 Btu per gallon and Biodiesel 130,000 Btu per gallon. Grades of fuel imply differences in composition and thus differences in combustion Btu values. Combustion values for ethanol will not depend on source of ethanol as long as ethanol content/composition is the same. Ali Hamza A_Hamza@yahoo.com
