Basically, we need 0.033 CFM per BTU of heating or cooling. That is equal to 1/30 CFM per BTU. In short, 30 BTU of heating and cooling is produced with 1 CFM of airflow; this is the BTU per CFM relationship. Based on this CFM per BTU conversion, we can check how many CFM do ...I feel like graphing calculators were only really a “thing” for most people during that year or two of high school when you were forced to use one for whatever math class you were ...Think of it as the balance in a complex recipe—just the right mix ensures perfection. Here’s the formula to break it down: airflow (CFM)= room’s floor area (sq.ft.) × ceiling height (ft.)× ACH÷60. airflow (CFM): The air volume flow rate you need in the room. room’s floor area (sq.ft.):.
