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
CFM is a rate of flow. KW is a rate of energy. You really cannot convert them.
formula for to convert gm to mmol
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.
3,960 feet per minute.
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.
Cubic Feet Per Minute, or CFM, refers to the measurement for finding the air volume velocity. It is calculated using the formula: CFM = (fpm * area); where fpm denotes 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.

To convert cmh to cfm ..... divide cmh by 1.7 to convert into 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.
Tr = cfm/400
CFM is a rate of flow. KW is a rate of energy. You really cannot convert them.
divide by 60
formula
1,000 cfm (feet3/min) is 0.4719474 m3/sec.
Take the number of cubic feet and divide that by the number of minutes. cfm=cf/m
FPM is feet per minute
