log 10 of anydrous ammonia vapor pressure. Uses formula shown below. Vapor-pressure formula for ammonia: [4] log 10 P = A – B / (T − C),
Gasoline gallon equivalent (GGE) or gasoline-equivalent gallon (GEG) is the amount of an alternative fuel it takes to equal the energy content of one liquid gallon of gasoline. GGE allows consumers to compare the energy content of competing fuels against a commonly known fuel, namely gasoline.
A 1 inch tall uranium fuel pellet is equivalent to about 1 ton of coal, 120 gallons of crude oil, or 17,000 cubic feet of natural gas. [15] In light-water reactors , 1 kg of natural uranium – following a corresponding enrichment and used for power generation– is equivalent to the energy content of nearly 10,000 kg of mineral oil or 14,000 ...
(1.292 - 0.090) kg/m 3 = 1.202 kg/m 3. and the buoyant force for one m 3 of hydrogen in air at sea level is: 1 m 3 × 1.202 kg/m 3 × 9.8 N/kg= 11.8 N. Therefore, the amount of mass that can be lifted by helium in air at sea level is: (1.292 - 0.178) kg/m 3 = 1.114 kg/m 3. and the buoyant force for one m 3 of helium in air at sea level is:
[1] For a fuel of composition C c H h O o N n , the (higher) heat of combustion is 419 kJ/mol × ( c + 0.3 h − 0.5 o ) usually to a good approximation (±3%), [ 2 ] [ 3 ] though it gives poor results for some compounds such as (gaseous) formaldehyde and carbon monoxide , and can be significantly off if o + n > c , such as for glycerine ...
The U.S. Energy Information Administration defines the barrel of oil equivalent as about 6 gigajoules (1.7 megawatt-hours; 5.7 million British thermal units). [1] The value is necessarily approximate as various grades of oil and gas have slightly different heating values.

[7] [8] A US liquid gallon can contain about 3.785 kilograms or 8.34 pounds of water at 3.98 °C (39.16 °F), and is about 16.7% less than the imperial gallon. There are four quarts in a gallon, two pints in a quart and 16 US fluid ounces in a US pint, which makes the US fluid ounce equal to 1 / 128 of a US gallon.
