If you know the FPM and you know the area of your flow say duct work (20"x20")...
first convert your area 20*20=400 in2 to Ft2
20"*20" = 400in2 400in2/144 = 2.7777Ft2
Now that you know the area in Ft2 you can use the equation [ FPM*area(ft2) = CFM ]
if your FPM is 500 and we use the 20"x20" duct then
500fpm * 2.777Ft2 = 1388.5 cfm

How to Convert cfm to kw?
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.
How do you calculate the speed of conveyor in feet per minute?
To calculate the speed of a conveyor in feet per minute (FPM), first determine the length of the conveyor belt in feet and the time it takes for one complete revolution of the belt in minutes. Use the formula: Speed (FPM) = Length of the belt (feet) / Time for one revolution (minutes). If the time is in seconds, convert it to minutes by dividing by 60 before performing the calculation.
How do you convert Pa to cfm?
You can't. Pascals (pa) area messurement of pressure. CFM (cubic feet per minute) is a rate of flow. However, there is a device called a manometer which is used to measure either pressure(in pascals) or air flow in(in cubic feet). Most commonly used for blower door tests.
What is the Formula for heat and air units?
The formula for heat and air units is typically calculated using the formula: BTU = (CFM x ΔT x 1.08) where BTU represents British Thermal Units, CFM is Cubic Feet per Minute, ΔT is the temperature change in degrees Fahrenheit, and 1.08 is a constant for air with a density of 0.075 pounds per cubic foot.
How do you convert kpa to cfm?
kpa = kilopascals is a measure of pressure. cfm = cubic feet per minte is a measure of the rate of flow. The two measure different things and, according to the basic rules of dimensional analysis, conversion from one to the other is not valid.
'What is the formula to convert FPM to 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.
How do you convert inches of water column into cubic feet per minute?
You can convert in w.c. to feet per minute and then convert fpm to CFM. FPm is 4005 times the square root of the pressure. So to convert 1 " w.c. to fpm its the square root of 1, which is 1 times 4005, which is 4005 fpm. Then you multiply the fpm by the area of the space the air is moving through. So if you have 1 " wc moving through a hole that's 1 square foot in area, that's 4005 cubic feet per minute.

If 1500 cfm of standard air is pushed through a 1x 72 slot what is the average slot velocity in feet per minute?
To calculate the average slot velocity in feet per minute (fpm), first convert the airflow from cubic feet per minute (cfm) to the area of the slot. The area of a 1-inch by 72-inch slot is 1/12 feet by 6 feet, which equals 0.5 square feet. Using the formula: [ \text{Velocity (fpm)} = \frac{\text{Airflow (cfm)}}{\text{Area (sq ft)}} ] [ \text{Velocity} = \frac{1500 \text{ cfm}}{0.5 \text{ sq ft}} = 3000 \text{ fpm} ] Thus, the average slot velocity is 3000 feet per minute.
How do you calculate the louver size?
To calculate louver size, start by determining the required airflow in cubic feet per minute (CFM) based on the specific application. Next, consider the velocity of air passing through the louver, typically measured in feet per minute (FPM). Use the formula: Louver Area (sq. ft.) = CFM / FPM. Finally, convert the area into dimensions that suit your installation, ensuring the louver meets any additional requirements for pressure drop and aesthetics.
How can you convert cfm to cmh?
To convert cmh to cfm ..... divide cmh by 1.7 to convert into cfm....
How to calculate cfm?
To calculate CFM (cubic feet per minute), you need to know the volume of the space in cubic feet and how many times you want to replace the air within one minute (air changes per hour rate). Multiply the volume of the space by the air changes per hour rate and divide by 60 to get the CFM required for that space. CFM = (Volume in cubic feet * Air changes per hour) / 60.
How to Convert cfm to kw?

How do you convert cfm to tr?
Tr = cfm/400
How can you convert btu to cfm?
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)).
How do you convert MMSCFD to CFM?
Coverting MMSCFD which is million standard cubic feet per day to CFM or cubic feet per minute requires knowing how many minutes are in a day. This can be determined by multiplying 60 by 24 and then dividing the MMSCFD by this product.
