Manufacturing Energy Flows in TBtuThe British thermal unit Btu or BTU is a non-SI, traditional unit of heat ; it is defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. It is also part of the United States customary units.
While units of heat are often supplanted by energy units in scientific work, they are still used in many fields. A BTU was originally defined as the amount of heat required to raise the temperature of 1 avoirdupois pound of liquid water by 1 degree Fahrenheit at a constant pressure of one atmosphere. This reflects the fact that the temperature change of a mass of water due to the addition of a specific amount of heat calculated in energy units, usually joules depends slightly upon the water's initial temperature.
As seen in the table below, definitions of the BTU based on different water temperatures vary by up to 0.
Units kBtu are used in building energy use tracking and heating system sizing. The unit quad is commonly used to represent one quadrillion 10 15 BTUs.
A Btu can be approximated as the heat produced by burning a single wooden kitchen match or as the amount of energy it takes to lift a one-pound 0. The Btu is often used to express the conversion-efficiency of heat into electrical energy in power plants. The centigrade heat unit CHU is the amount of heat required to raise the temperature of one pound of water by one degree Celsius. It is equal to 1. From Wikipedia, the free encyclopedia.

Copyrights - All Rights Reserved.A British thermal unit Btu is a measure of the heat content of fuels or energy sources. It is the quantity of heat required to raise the temperature of one pound of liquid water by 1 degree Fahrenheit at the temperature that water has its greatest density approximately 39 degrees Fahrenheit.
A single Btu is very small in terms of the amount of energy a single household or an entire country uses. Inthe United States used about Written out, 1 quadrillion is a 1 followed by 15 zeros: 1,, Energy or heat content can be used to compare energy sources or fuels on an equal basis. Fuels can be converted from physical units of measure such as weight or volume to a common unit of measurement of the energy or heat content of each fuel.
The U. EIA collects data on the physical amounts volume or weight of energy sources produced, imported, exported, and consumed. EIA converts those amounts into Btu equivalents to compare the sources on an equal basis. For example, the physical volumes of fossil fuels consumed in the United States in and Btu equivalents were.
A cord of wood is a volume unit and does not take wood density or moisture content into account. Wood heat content varies significantly with moisture content. The Btu conversion factors above are approximations. EIA provides more heat contents for fuels and electricity in the appendices of the Monthly Energy Review.

It is used in the United States mainly to produce heat and generate electricity. Innatural gas accounted for 31 percent of total U. Natural gas is measured in the U. Feet are an increasingly outdated form of linear measurement, and correspondingly, cubic feet cf or ft 3 are no longer a common unit of volume in the world at large, with meters m and cubic meters m 3 now the global standard for length and volume.
The energy sector, however, continues to use old-school measures of heat and volume. Heat, rather than being measured in joules Jis usually traded and sold in terms of British thermal units Btu.
The amount of heat in a given volume of natural-gas-containing soil varies temporally and geographically, so the amount of Btu per cf varies slightly from place to place and from year to year. It is important to note that prefixes are used in natural-gas measurements that mean something different than in other physics context.
Specifically, "M" refers to "one thousand times" when referring to cubic feet of natural gas, instead of the standard "k" for "kilo-"and "MM" indicates "one million times," in contrast to the "M" "mega" seen most often.
Finally, "C" denotes "one hundred times," not to be confused with small-c "centi-" meaning "one hundredth.
A Ccf is thus the amount of gas in cubic feet of soil, an Mcf is the amount in 1, cubic feet and an MMcf is the amount in one million 1, or 10 6 cubic feet. One meter is equal to 3. This relationship can be used to relate volumes in the respective units to one another. One cubic meter is 3. The Btu is defined so that under unvarying conditions over time and around the world, 1 cf should yield 1, Btu, or 1 MBtu, or heat.
But because of the aforementioned correction factor, this varies slightly. For example, inthe amount reported was in fact 1, Btu 1. Once you know the most recent conversion factor to adjust the 1.
First, if need be, convert cubic meters to cubic feet by multiplying by In view of the importance of these publications, it is reasonable to view the IT calorie as being the preferred unit for discussions of energy production and use, but there is no universally adopted practice see also the discussion of Btu, below. Sometimes a capitalized version, Calorie, is used to denoted the kilocalorie kcal.
In discussing food, the "calorie," capitalized or not, is always the kilocalorie. As for the calorie, there is a family of "Btu's" in relatively common use, including:. The relationship between the kWh and the Btu depends upon which "Btu" is used. It is common, although not universal, to use the equivalence:.
This corresponds to the International Table Btu. Given the wide variations in the actual heat content of fuels, especially oil and coal, it is common to introduce a nominal energy equivalent that reflects a typical energy content of the given fuel, but is decoupled from the variations that occur in actual fuels.
The energy equivalent can be considered to be an alternate energy unit, precisely related to units such as the joule, calorie, or Btu. Energy equivalents for oil and coal are discussed in succeeding paragraphs, below, and are listed in Table 1.
Conversion factors for oil. The heat content of crude oil from different countries varies from about 5. The heat content of typical petroleum products varies even more see Table 1.
A nominal conversion factor is sometimes used for a barrel of crude oil, which is close to its actual average energy content:. With this definition, a correspondence can be established between millions of barrels of oil per day Mbd and quads per year:.
An energy equivalence for oil can also be specified in terms of energy per metric ton tonne. For the United States, the average was 7. This average, together with the nominal equivalence of 5. There are differing definitions in the literature of a tonne of oil equivalent toe. These choices correspond, respectively, to:. A corresponding larger unit, the gigatonne of oil equivalent Gtoe can be related to the exajoule and quad:.
