Hi,
How can I calculate damper (vent) size for blowing 110 CFM across it? I want to use natural convection. (i.e warm air from sunspace is vented to another zone through this vent).
Thanks
DBS

RE: damper
This is going to be very little pressure, so the larger the duct, the better the heat transfer.
Borrow a duculator or read ASHRAE for duct pressure drops.
