Thanks for the replys.
Lurch, I agree with your suggestion about closing the soffit vents. Sooner of later either the gable or ridge vent will turn into intake instead of exhaust.
Unfortunately, I don't have the resources, (measuring instruments, facilities, etc) or the smarts(Reynolds...
Already set up for a different model, but it shows the path of the smoke.
There is air going in at the soffits. Otherwise no air would be coming out the top.
The lighting is probably the hardest part of the whole darn experiment!

Hi Lurch, thanks for the reply.
The roof model is closed on both ends with small cut outs to simulate gable vents. A sealed attic floor is below. There are openings at either eave/overhang to simulate soffit vents.
The smoke is incense. I used that to simulate the hot air that is in the...
I have been trying to find some information or study concerning a widely held idea concerning attic ventilation.
Conventional wisdom states that when air passes over the ridge vent on the peak of a house, the resulting low pressure will draw air from the attic. The air that is removed from the...
Thanks Fred,
I think you understand what I'm getting at, but I really don't know the best way to make the notations.
I had read in a ventilation manufacturers specifications that the upper vents should not be installed as in the diagram. The idea being that there would be stronger low...
Hi all, I need to know if I'm on the right track with my thinking. I've drawn a diagram that hopefully is not too simplistic and shows what I am getting at. One of these links should work.
