iv'e never tried to insert a link into text before. and looks like it worked! LOL
Sorry, i was referring to the stack length. If the calculator says with a 4" diameter pipe I would need to have a stack length of 20.4". Does this mean from the top of the cooking chamber, grate level or does it just require 20.4" of 4" diameter pipe no matter where it's placed?
if ya mean for this build i haven't had the time to make any significant progress to make some qview. i should be starting this week and have some progress to post.
hey controlfade, the 20.4 " is the total length of the stack. i start mine at the top of the cooking chamber, some people like to put theirs closer to the grate.
duck how would that calc work if i'm using a round 150 propane tank with football shaped opening from SFB to cooking chamber....using that calc i came up with a big hole needed between to two....without going and making a square smoker to make all holes easier to make ...........bob
ok here is a crude drawing of what i mean with the red area is what i'll have when i make the two meet each other....
how would i figure the area of this shape with the calc posted you used..........bob
