Carbon dioxide emissions vary depending on the fuel. Natural gas (the cleanest fuel) produces about 117 lb CO2/106BTU. Coal, on the oter hand, produces about 225 lb CO2/106BTU. Liquid fuels (gasoline, diesel and furnace fuel) are in the middle of the range.
The equivalent of about 6,330,000,000 joules or 6 million BTUs
1 gallon for #1 Kerosene produces 135,000 BTUs. #1 Kerosene is closely related to #1 Diesel and JP8 (Jet Fuel) - they differ chiefly in additives. Likewise, #2 Kerosene, Diesel #2, and Furnace Oil are similar to one another. #2 oils have higher sulfur content, which leads to more eye and lung irritation from the emissions. However, they are also comprised of longer hydrocarbon chains, and therefore weigh more per gallon and also have somewhat higher energy content.
1 BTU is the energy required to heat 1 pound of water by 1 degree F. 1 Joule is defined mechanically, but in thermal terms it is 1/4.2 of a calorie (4.2 Joules/calorie), and 1 calorie is the energy required to heat 1 gram of water by 1 degree C. In fact 1 BTU = 1055 Joules.
1)This is a 5 part question. The first is realizing that 20F to 32F uses .5BTU per pound per degree. That means it takes 32-20=12*.5=6BTUs to get the ice to 32F. 2)Then you need to know the Latent Heat of Fusion for Ice which is 144BTUs (given). Lets assumes the ice changes from ice to water instantaneously at 32F. 3)Next we calculate the BTUs from 32F to 212F. Which is 1BTU per pound per degree F. 212-32=180 so it take 180BTUS. 4)Next we have to use the Latent Heat of Vaporization of water which will say instantaneously converts water to vapor. This takes 970BTUS (given). 5)Then we calculate the BTUS from 212F to 220F. Which is .5BTUs per pound per degree F which is 220-212=8*.5=4BTUs...... Finally add up all the BTUs and you get 6+144+180+970+4=1304BTUs.
LATENT HEAT OF FUSION When one pound of ice melts, it absorbs 144 BTUs at a constant temperature of 32°F. If one pound of water is to be frozen into ice, 144 BTUs must be removed from the water at a constant temperature of 32°F.
The sulfur content of coal and its heating values are not constant across all grades of coal. It would require information of type of coal, carbon content, sulfur content and ash content to even start the calculation.
There are approximately 6,700-8,300 BTUs per pound of lignite coal. A ton of lignite coal contains 20-24 million BTUs.
17 million btus in 5 million watts
Around a million. plus or minus a few.
Low- and medium-volatility grade bituminous coal typically generates between 26 and 30 million BTUs per ton.
To calculate the amount of energy required to produce steam, we need to know the specific enthalpy of water and the temperature/pressure conditions. Generally, it takes about 1,000 BTUs to convert 1 pound of water at 212°F to steam. Therefore, for 32 million pounds of steam, it would require approximately 32 million BTUs, or 32,000 MMBTUs (using the conversion that 1 MMBTU = 1,000,000 BTUs).
1 kWH = 3.6 megajoules of energy and 1 BTU = approximately 1055 joules.1 kWH = 3412.3 BTUSo a million BTUs would be 3.4123 billion BTUs (3.4 x 109 BTU)However, this is not an exact conversion because kWH is energy exerted over time, while BTU is energy content.(see the related question)
The number of BTUs per cord of wood depends on the type of wood. One cord of cottonwood is equal to 16.1 million BTUs. One cord of hard maple is equal to 23.7 million BTUs, and one cord of red oak wood is equal to 24.4 million BTUs.
The equivalent of about 6,330,000,000 joules or 6 million BTUs
Approximately 5,800,000 BTUs per 42-gallon barrel.
To convert therms to BTUs, you can use the formula: 1 therm = 100,000 BTUs. Therefore, to convert therms to BTUs, simply multiply the number of therms by 100,000. For example, if you have 2 therms, the calculation would be 2 therms × 100,000 BTUs/therm = 200,000 BTUs.
High-volatile coal, in contrast, usually produces anywhere from 18 to 29 million BTUs per ton.
