What is CFH in gas flow rate?
1 Cubic Foot per Hour: Volume flow rate of 1 cubic foot in a period of 3600 seconds. Assuming a cubic international foot. 1 Cubic foot per hour is approximately 0.000 007 865 790 72 cubic meters per second.Click to see full answer. In this regard, how do you calculate CFH?The equation explains that one cubic foot per hour, or CFH, is equal to 1,000 BTU of natural gas or 2,500 BTU of liquid propane when exposed to the environment. Multiply the BTU number that needs to be converted by the correct factor from the equation, depending on whether natural gas or liquid propane is being used.Also Know, how many BTU is CFH? The BTU’s per hour unit number 2.72 Btu/h converts to 1 atm cfh, one atmosphere cubic foot per hour. Consequently, what is CFH in natural gas? A therm’s worth of natural gas contains 96.7 cubic feet/therm, or about100 cubic feet/therm. To calculate the CFM (ft3/min) or CFH (ft3/hr) for 500,000 BTUs per hour of Methane we have: 500,000 BTU/hr ÷ 100,000 BTU/therm = 5 therms/hr.Is CFM a mass flow rate?The term cubic feet per minute (CFM) is ambiguous when it comes to the mass of gas that passes through a certain point because gas is compressible. If the pressure is doubled, then, for an ideal gas, the mass of the gas that passes by will also be double for the same rate of flow in cubic feet per minute.
