There are 400 cfm in 1 ton
Take the number of cubic feet and divide that by the number of minutes. cfm=cf/m
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
You need 350 to 400 cfm per ton (12,000 btu) of cooling. So, divide your cfm by 400. For example, a 1200 cfm blower on an air handler could handler up to 3 tons. All calculations depend on your duct being the proper size for the equipment.
Roughly about 130 decibals per "scream".
Extremely Loud and Incredibly Close is approximately 130 minutes long.
To convert cmh to cfm ..... divide cmh by 1.7 to convert into cfm....
Tr = cfm/400
750 CFM
5-10 cfm = -5
1tr = 400 cfm
CFM International was created in 1974.
