# How can you convert btu to cfm?

# What is a BTU?

hi ashley The British thermal unit (BTU or Btu) is a unit of energy used in the United States. It is also still occasionally encountered in the UK, in the context of older heating and cooling systems. In most other areas, it has been replaced by the SI unit of energy, the joule (J). A Btu is de…fined as the amount of heat required to raise the temperature of one pound avoirdupois of water by one degree Fahrenheit. 143 Btu is required to melt a pound of ice. As is the case with the calorie, several different definitions of the Btu exist, which are based on different water temperatures and therefore vary by about 0.5%.

# Convert CFH to BTU?

To convert CFH to BTU, you need to use the formula 1 CFH which isequivalent to 1000 BTUs.

# How do you convert BTU to KW?

BTUs and kilowatts measure different types of quantities. A BTU (British Thermal Unit) measures heat (energy), while a kilowatt (1000 watts) measures power (energy per unit time). 1 BTU equals 0.0002928 kilowatt-hour 1 BTU/minute equals 0.01757 kilowatt. To convert a watt to BTUs, the factor… is 1 kilowatt of power = 3412.1416 BTU/hr 3.412 BTUs equal a watt-hour. 1 kW = 3412.1416 BTU/hour with appropriate significant figures 3*10 3 BUT per hour (MORE)

# If 10000 Btu per hr are added to 100 CFM of air at 32 degrees F what will the final temperature be?

You're looking for the "delta T" for this equation.....
Q = cfm * 1.08 * dT and 10000 = 100 * 1.08 * dT ==> dT = 92.59.
the final temperature will be 32 + 92.59 = 124.59 degF

# How do you convert a volume of hot gas to btu?

There is no direct conversion because it depends on the gas. A BTU is a unit of energy (a "British thermal unit") and how much energy a certain volume of gas has depends on the identity of the gas. A liter of gaseous oxygen will have a different amount of energy in it than a liter of hydrogen gas. … Also, it depends on the temperature and pressure of the "hot gas." Because of the Ideal Gas Law (see Related Questions links), the amount of gas in the same volume goes down the hotter the gas. If you know the temperature and pressure, it is easy to find how much gas you have in a certain volume. Then, to convert that to BTU, you need to know the energy content of that specific gas. That you need to look up in a table somewhere... .
Agree with JEK above..
The short answer: It depends on the type of gas, and whether the gas is hot or cold changes the density of the gas. So standard atmospheric temperature and pressure should be taken into consideration.
The long answer: To convert a volume of any gas into a unit of energy, you have to know what kind of gas it is first. The Btu content of a gas is determined by the percentages of its component gas. The higher the Btu rating of the gas, the more energy it contains per cubic foot or volume of that gas. Take Natural Gas for example. NG is a mixture of several different gasses, mostly methane. This being the case, no two wells that produce NG have the same energy content. There is no true standard of energy content (or calorific value) for NG. For rough estimates an average value can be used: it is roughly 1000 Btu/ft^3. A standard heating value for domestic and commercial NG delivery is 950 Btu/scf (scf=standard cubic feet). There are references on the Btu content of specific gases. There are also conversions..

# How do you convert refrigeration tons to BTU?

This conversion is very simple : and is 1 ton = 12,000 BTU/hour. So if you have a 3 ton of refrigeration you have 36,000 BTU/hour. In addition, I want to add that in some large Data Centers, there is a movement from BTU to kW of power used by equipment. This is probably driving the Tons/kW quest…ion that the HVAC engineers are telling people cannot be solved. 1 Ton of cooling will eliminate 12,000 BTU /hr of heat. 12,000 BTU /hr will be produced by 3.516 kW of power used by equipment. 1 Ton of cooling will then handle 3.516 kW of equipment load based heat exhaust.

# Convert CFM to CMH?

We're going out on a limb here, taking a chance, throwing caution to the wind, risking looking stupid, and assuming that 'CFM' means 'cubic feet per minute' and 'CMH' means 'cubic meters per hour'. ( 1 ft 3 / min ) x x (1,440 min / hour) / (35.3147 ft 3 / m 3 ) = 40.776 CMH (rounded)

# How do you convert BTU's in CFM?

The answer depends on many things.... A btu is a british thermal unit, which is the measure of energy to raise one CC of water one degree Celcius. But you probably want to know about airflow in cfm (not water), and the amount of cooling (or heating) available in 1 cfm or airflow. In Houston, we tend… to cool things more than heat. We also try to drive moisture out of the air (dehumidify), but I won't discuss that now. The general equation to answer your question is like this: Q sens = cfm * 1.08 * (T in - T out ) 23.76btu/h) (MORE)

# How do you convert kwh to btu?

1 BTU = 1.055 kilojoules. (1 joule per second = 1 watt, or 1 joule = 1 watt-sec) 1 kWh = 3.6 megajoules (1000 x 3600 watt-sec = 3600 kilojoules) 3600000/1055 = 3412.3 So 1 kWh is the energy equivalent of 3412.3 BTUs . The reverse conversion is that 1 BTU = 0.000293 KWh * However, a …kWh is energy used in work over time , while BTUs are energy content . WattHours (Wh) or BTU's are measurements of Energy: which is how much energy is used (a certain amount). Conversely, watt and hp are measurements of power, which is how fast energy is being used (a certain rate). Over the last century Wh, KWh, and MWh has replaced BTU in all non-heating uses of energy, except in scientific use (prefers the joule, J). In describing thermal energy use however, BTU (larger amounts of energy) and calories (smaller amounts of energy) and sometimes therms (very large amounts) are still used. (MORE)

# What is 41.3 cfm converted to meters per second?

CFM is a Volumetric Flow Rate while m/s is a velocity, you need the additional measurement of the Cross Sectional Area of the flow to fully work it out. Since there are 2118.88 CFM : 1 m 3 /s 41.3 CFM divided by 2118.88 = 0.01949 m 3 /s Divide this by the area in m 2 & you will get m/s. .

'Gallon' is a unit of volume or occupied space. 'BTU' is a unit of work or energy. The two units measure different quantities. Neither one can be converted into the other one.

# Convert degree of Fahrenheit to btu?

Degrees Fahrenheit are a unit of temperature and British Thermal Units are units of heat; in physics, temperature and heat are not the same thing (although they are synonymous in normal English usage). To explain, the heat content of an object depends upon both the temperature and the heat capacity …of that object, so for example, one liter of water has only half the heat capacity of two liters of water; even if your one liter container is at exactly the same temperature as the two liter container, it still has only half the heat content as measured in BTUs. So, since these units do not measure the same thing, they cannot be converted into eachother. (MORE)

# Convert btu per month to KWH?

"BTU per month" is a rate of energy consumption, i.e. "power". The two quantities have different dimensions. They don't convert to one another. But lets play with them for a while anyway: (1 BTU/month) x (1055 joule/BTU) x (month / 30 days) x (day / 86,400 seconds) = ( 1055 / [30 x 86,400] ) ( BTU - joule - month - day / month - BTU - day - second) = 0.000407 joule per second = 0.000407 watt That's the rate of energy consumption (power) equal to one BTU per month . . . . . 0.407 milliwatt (or -3.9 dBm). ======== (1 KWH) = (1,000 watt-hour) = (1,000 joule / second) (hour) (BTU / 1055 joule) (3,600 sec / hour) = [ (1,000 x 3,600) / (1,055) ] [ joule - hour - BTU - second / second - joule - hour ] = 3412.3 BTU That's the amount of energy equivalent to 1 KWH . . . . . 3,412.3 BTU.
