but if I was to take some 3" exhaust pipe and extend my stack. Based on what has been said I would in theory have better air flow and better temp control...... Any thoughts?
jjc, evening... You will still have "friction loss" from the side walls of the pipe... Longer is better but a 1/2" hose will deliver the same amount of water at a given pressure whether it is 50' or 100'.... Once you get to the friction vs volume, ain't nothing you can do.... it's physics .... In this case, as in most, BIGGER is better.... :biggrin: ..... Have you lowered the stack to somewhere near the grate ??? that adds to the friction also... Just trying to save you some work.... I hate doing things 2, 3 or even four times... I have done that enough, that I know, if you can't engineer it, over build it.....
