    USA coil Software (problem )



    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 ...
