pipe diameter?
 

Is there any type of cheat sheet somewhere that gives the pipe diameter for certain size turbines? I'm mainly interested in the diameter for a K320. Also want to know if the 320 is limited to 50 or so pounds of thrust, can I use a smaller diameter? I have a scratch build project starting soon, and a 110mm is all I can fit. I already have a 320 sitting on the shelf and would rather not buy a smaller engine.

Thanks!

Fred,

Not a 320 specifically, but the Jets Munts manual gives minimum pipe sizes for their engines. It might be a starting point for you.

Plotting pipe size by both diameter and area and extrapolating gives a minimum pipe diameter for a 320 as 100mm.
