WebTo calculate the air change in a room, the airflow is measured (CFM) and multiplied by 60 minutes per hour. It is then divided by the volume of the room you wish to measure (in cubic feet): Air Changes / hr = (CFM x 60 minutes) / Volume of the room (cubic feet) WebMar 28, 2024 · cfm = BTU/hr / (1.08 x ΔT) And there we have it. Once we know how much heat a room needs to have supplied or removed, we can do a simple calculation to see how many cubic feet per minute of air flow we need. Of course, the cfm we need will depend on the location. You can’t just use 1.08 everywhere, as I said above. find file with name powershell
