To convert Btu per hour to CFM per minute, take the energy transfer rate in Btu and divide it by 100,000. Multiply the result by 96.7. Divide that result by 60 to devise the gas transfer rate in cubic feet per minute.
Continue ReadingThe Btu has to be divided by 100,000 because that is the number of Btu in a therm. A therm of gas has a volume of 96.7 cubic feet. This number is sometimes roughly estimated to be 100 cubic feet rather than the more specific 96.7 cubic feet because it is typically an easier number to utilize in mathematical equations, though the resulting number would be more of an estimate rather than an actual result. The result of that equation is divided by 60 because that is the number of minutes in an hour. It is possible to convert between Btu and CFM because the energy of the gas is equal to the gas's volume.
The therm is the most common unit of measurement for natural gas. Btu are used once the amount of therms climbs above 100,000. In addition to being equal to 100,000 therms, the Btu is equal to 105.5 megajoules and 29.3 kilowatt-hours of energy.
Learn more about MeasurementsTo convert from normal cubic meters per hour to cubic feet per minute, it is necessary to convert normal cubic meters per hour to standard cubic feet per minute first. Once the conversion is made, determine the actual pressure and temperature of the flow, and use a conversion equation to find the flow in cubic feet per minute.
Full Answer >CFM, or cubic feet per minute, denotes the unit of compressed airflow for air conditioning units. SCFM stands for standard cubic feet per minute, a measurement that takes into account standard conditions. Cubic feet per minute indicates how much air flows through air conditioning as the machinery pushes air through ducts of a building. An air conditioner produces roughly 400 cubic feet per minute per ton of cooling capacity.
Full Answer >The CFM rating of a bathroom fan is a measurement of how many cubic feet of air it can ventilate out every minute. To vent a bathroom properly, the bathroom fan must have a CFM rating that is able to change the air eight times every hour.
Full Answer >Cubic feet per minute, or CFM, is calculated by using a combination of air velocity and volume measurements. CFM is usually used to measure how much air flows through a given heating or cooling system in a set amount of time.
