How many therms are there in a cubic meter of natural gas at atmospheric pressure?
100 cubic feet equals 1 therm
According to U.S. EPA, Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2004, 1 therm of natural gas burnt produces 11.7 lbs. of carbon dioxide emissions. Theref…ore, the Carbon Coefficient for natural gas is: 117 pounds of CO2 per million BTU, or 0.12 pounds per cubic foot of gas.
Liquified natural gas has about 1/600th of the volume of natural gas at standard temperature and pressure, so 1 m3 of natural gas would be about 0.001666 m3, or 1.67 liters, o…f LNG.
1 Therm = 100,000BTU
One Cubic Meter of natural gas is approximately 36000 btu.
There are 1000 liters in one cubic meter. 22.4 liters of any gas is equal to 1 mole, according to molar volume. Molar mass tells us that the main component of natural gas, met…hane, or CH4, has a molar mass of 12+1+1+1+1, or 16g per mol. 16g/mol * 1000L/m3 / 22.4 L/mol = 714g/m3 = 0.714kg/m3 Therefore, there are 0.714 kilograms in a cubic meter of natural gas. You must remember that this only applies under certain conditions. The 22.4 L/mol number is a result of the Ideal Gas Law PV=nRT. In order to equate volume with moles, P and T must be specified (R is a constant). Only at atmospheric pressure (1atm) and standard temperature (0 Celsius) is there 22.4 liters in a mole of gas.
The "therm" is a unit of energy often used in connection with various methods of home heating ... gas, oil, electric, etc. 1 therm = 100,000 BTU = 1.055 x 10 8 joules … That's the easy part. The next question is: How much energy do you get by burning a cubic meter of natural gas ? The references we found on line listed the following answers (in mega-joules): 37, 40, 37, 19 to 56, 37 to 41, 39, 38. Instead of agonizing over which one is correct, let's say there's a grain of truth in all of them, and take an average ... 38.21 megajoules per cubic meter. OK. Now we're ready to do the conversion for you: ( 1 therm / 1.055 x 10 8 joule ) x ( 38.21 x 10 6 Joule / cubic meter ) = 0.362 therm / cubic meter 2.761 cubic meter / therm . Your answer is: Multiply therms by 2.761 to find out how many cubic meters of gas you need to burn in order to produce that much heat.
1 Therm is 100,000 BTU, and as there are 1000 BTU in 1 cubic foot of gas, 1 Therm = 100 cubic feet. Density of methane = 0.72 kg/cubic meter which is 35.3 cubic feet, so… 100 cubic feet = 2.04 kg
it has about 1031 btu in one cubic meter!!!!
"I think it's just under 11 (10.86), my gas bill currently shows 1843.52 m3 which is converted to 19991.kWh. It is 10.83KWh/m3.". According to http://www.ukenergy.co.uk/page…s/gas-kwh.html ...... Multiply m3 by a correction factor of 1.022640 and then by the calorific value shown on your last gas bill (39.1 for me). Finally divide the result by 3.6 to give kWh.
That depends upon the temperature, pressure, and type of gas. For more information, study the ideal gas law. One form of the ideal gas law is PV=nRT, where P=pressure, V=volum…e, n=number of moles of gas, R=0.08206 L-Atm-mol-1-K-1, T=temperature in degrees K. By rearranging this equation, you could calculate the number of moles of gas if you knew the volume, temperature, and pressure of the gas. Then multiply by the molecular weight of the gas to get the grams, and divide by 1000 to get kilograms.
A therm of natural gas sold to me for home use by Questar Gas cost 92 cents. The cost of a natural gas varies depending on what state you live in. Utah has the lowest co…st of natural gas.
