"CFM" and "CMH" are rates of flow, typically of air or other gases, used to describe the capacity of an HVAC or air handling system, or of a fan. CFM = cubic feet per minute CMH = cubic meters per hour (1 ft3/min) x (meter/3.28084 feet)3 x (60 min/hour) = 1.7 m3/hour 1 m3/hour = 0.5886 ft3/min
1TR = 3.5 KW 1TR = 3.5 KW
To convert cmh to cfm ..... divide cmh by 1.7 to convert into cfm....
divide by 60
1 tr is equivalent to how many hp?
Cubic feet per minute (CFM) and gallons measure different things: CFM is a unit of volumetric flow rate, while gallons measure volume. To convert CFM to gallons per minute (GPM), you can use the conversion factor where 1 cubic foot equals approximately 7.48 gallons. Therefore, to convert CFM to GPM, you would multiply the CFM value by 7.48.
To convert cfm (cubic feet per minute) to kW (kilowatts), you first need to know the efficiency of the system. Once you have the efficiency, you can use this formula: kW = (cfm x pressure x efficiency) / 229. upheld wp-admin css where pressure is in psi.
1,000 cfm (feet3/min) is 0.4719474 m3/sec.
To convert BTU (British Thermal Units) to CFM (Cubic Feet per Minute), you need to know the specific heat of the material being heated or cooled. The formula to convert is: CFM = (BTU/hr) / ((Temperature rise in °F) x (Specific heat of material)).
1 cubic foot per minute (CFM) is equivalent to approximately 28.3168 liters per minute (L/min). Therefore, to convert CFM to liters, you can multiply the CFM value by 28.3168. For example, 1 CFM is about 28.32 liters per minute.
Cmh = cubic meters per hour cfm = cubic feet per minute m3/hr * 35.3ft3/m3 * hr/60minutes = ft3/minute So, 1 cmh = 0.5883 cfm

To convert Feet Per Minute (FPM) to Cubic Feet Per Minute (CFM), you need to multiply the FPM value by the cross-sectional area of the duct or opening in square feet. The formula is: [ \text{CFM} = \text{FPM} \times \text{Area (sq ft)} ] Make sure to measure the area in square feet for accurate conversion.
