I have no real idea, but I am going to venture a guess.

No.

I'm thinking it is the total area of the chute that you need to consider.

The area of a 24" chute in square inches is 452.blah blah blah.

The area of a 12" chute is 113.yadda yadda yadda.

So two 12" chutes have 226.something.

Looks to me that you would need

** 4 ** 12" chutes to equal one 24 incher.

Which would make sense with the whole

* squares * thingee.

Unless of course I'm wrong, in which case you are actually dreaming and this was never written and I've been right the whole time since it was never posted.

Now, let's see who busts me out.
