New to SMF with a new build

I  am using the reverse flow calculator and circle calculator and have some questions if someone can help me.

 

1. The diagram of the reverse flow smoker picture shows the stack going down inside the cook chamber. Is this true and what would be the height above the cooking grates?

2. I have calculated the volume of the cook chamber, but one end is eliptical ( a propane tank), How will this affect the volume if I use the total length.

3 For the exhaust stack length is that formula ESV divided by 0.7854 x Stack Diameter x Stack Diameter?

 

Thanks in advance for any help. This is a great group for ideas and learning.

Hello Lou, welcome to the forum!

Sounds like your build is very similar to the one I just completed, 120G propane tank.

1) on my build, my stack comes down about 3" into the cook chamber. Some go lower, it's a personal preference thing.
2) I used the Feldon's calculator, it takes out the guesswork. Enter the gallons value in the "tank" field
Your post did not specify which calculator you're using. so here's what I used: http://www.feldoncentral.com/bbqcalculator.html
3) The typical formula for the exhaust stack capacity is 5% of firebox volume. Again, the calculator helps a lot with this.

I also want to throw in that fact that when I built by RF cooker, I heavily relied on the input of people on many threads in this forum.
I will be posting images of my build soon!

Good luck to you and look forward to seeing your build pics!
