Now, the air velocity relates to that special ratio of cfm/ton, too. When the air moves at a lower velocity (feet per minute, fpm), it also has a lower air flow rate (cubic feet per minute, cfm). So by slowing the air down, the cfm/ton goes down, too. (Let’s ignore for n...
If the exhaust vents are too small, the airflow could be inadequate to prevent smoke buildup inside the house. A range hood typically operates between 200 and 400 CFM. Does the Type of Range Hood Matter? Yes! Every model will come with its own unique perks, which could influence its CF...
Stove-top size: The vent hood fan should move 100 cfm of air for each 12 inches of stove width. A 3-foot-wide stove, then, requires a 300 cfm fan in the vent hood. Room size: Some designers follow a rule that dictates that a vent fan should be able to move an a...
Not every MRI requires using a contrast agent. MRIs with and without contrast are both effective, and your doctor will determine which scan you need based on your present condition and your medical and health history. But, if the doctor requires a highly detailed image to assess a specific pr...

but many are still influenced by how much CFM your exhaust stacks are pulling. If one stack has more flux build up than the other this will cause each oven to have slightly different thermal behavior. Many oven controllers can have a +/- 5 degree C variance. If you think about it, in...
Air Conditioner Test Data & Results 1. Operating Noise (dB) All air conditioners make noise, this is a fact. Generally speaking, the more airflow an A/C unit has, the louder it’s going to be, and (logically) the more capable it is of cooling larger spaces (or smaller spaces more ...
Some guests like a reason to get even more dressed up so they pack a tuxedo or gown. If getting dressed up isn’t your thing, smart casual attire is acceptable for dining and the theater shows. Swimsuits, see-through cover-ups or robes, tank tops, baseball hats, and pool wear are pr...
