nLPM stands for Normal Liters per Minute. This is actually a mass flow rate because it describes the amount of gas that would have the indicated LPM volumetric flow rate AT 1 atmosphere pressure and 0 degrees C. The actual volumetric flow rate (LPM) at any other temperature or pressure condition must be adjusted according to the ratios of absolute temperatures and (inversely) absolute pressures.
1 cubic foot per minute (cfm) is approximately equal to 28.3165 liters per minute (lpm) at standard conditions. To convert cfm to normal liters per minute (nlpm), you typically need to account for specific temperature and pressure conditions, but under standard conditions, 1 cfm is roughly equal to 28.3165 nlpm.
Conversion from LPM to NLPM: NLPM = LPM * (273.15/Tgas)*(Pgas/14.696) Where Pgas is absolute pressure in PSI Tgas is gas temperature in Kelvin e.g. Convert 1000LPM to nLPM value by considering the gas temperature 30 deg. cel. & absolute pressure 1 bar NLPM = 1000 * (273.15/303.15)*(14.50377/14.696) NLPM = ~ 890 - Sanjay Rajput (Pune)
To convert cmh to cfm ..... divide cmh by 1.7 to convert into cfm....
Tr = cfm/400
divide by 60
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)).
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.
