Ductulator Usage
(OP)
If you are sizing a duct supply for 2" w.g. what friction loss unit do you line up with the air volume. Is it .02, .2, or 2? Additionally I'm looking for a good easy to use HVAC load computer program. Any recomendations?

I am not sure what you are asking so rather than try to answer and look stupid I'll just wait for some clarification. :)

For your second question, EnergyPro is an easy to use Windows-based program. CHVAC is an easy DOS-based program using the Manual J method.
