There are 400 cfm in 1 ton
Take the number of cubic feet and divide that by the number of minutes. cfm=cf/m
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.
Well, darling, CFM stands for cubic feet per minute, while CMH stands for cubic meters per hour. So, the relationship between the two is that 1 CFM is equal to approximately 1.699 CMH. It's like comparing apples to oranges, but hey, they both measure the flow of air, just in different units.
your going to get 800 cfm through a 20x20. Its the gross square inches divided by 2
Check the air flow per cubic meter of your diffuser area cover in your unit. CFM= cubic feet per minutes.
from my experience the 750 cfm will dump too much fuel you should go with a 600 cfm. i prefer the holley. you should only go with a 650 or 750 cfm if you have 400 horsepower of more.
600 cfm will be enough for that engine.
~ 1000 cfm
600 cfm should be just right for a stock or slightly modified 350.
2200 to 2500 cfm's Hayden has a chart on the Box. for elec. fans
For better comfort you should go with 1.5 cfm per sq foot. Depending on how many windows and solar gain, you can increase the cfm.
All the three CFA,CFM and CFP are better for the future as far as the finance majors is concerned.
To convert cmh to cfm ..... divide cmh by 1.7 to convert into cfm....
Tr = cfm/400
750 CFM
300 cfm should do it.
