    duct traverse

    when taking a duct traverse i know its ten X upstream or 5 X downstream, but what do you multiply to get five times. the short side of the duct, or the square feet of the smaller duct.

    you are trying to make sure you don't get turbulents. I don't remember what it is for rectangular but take the area, convert to round and you'll be real close.

    The way we build has a greater impact on our comfort, energy consumption and IAQ than any HVAC system we install.
