Hi
when rating a condenser in usa coil software, there is CFM for axial fan.( my axial fan has a label for example 4000 cfm).
which one is correct for cfm in software:
1-SCFM
2- ACFM
3- determine cfm with a velocity meter device

if i dont have a Velocity metering device, what is the reasonable number for CFM.

thanks

Hope this will help a little ... not sure what to suggest you but for sure try to calculate with the best options and with the worst ... to see the difference ...

... calculations are not the numbers only ... sometimes (mostly of time) it is a game ...
