Hi !
Can you post here the value of air pressure you have to use function of the mix (1x 2x 3 x 4x .? )
thanks
Pressure f(mix)
A^2(B/C)^2(X*Y*Z)^2 /100 = Air pressure needed in the cannon chamber
A= Propane Percent [In decimal form EX: for 50% put .5]
B= Atomspheric Pressure [Usally from 13.7 - 14.7]
C= Temperature
X= Flow Coef
Y= Max Restriction [In inches]
Z= Hybrid Atomziation Pressure [Already figured at 37.8 roughly]
EDIT - I simplfyed the work involved removing all the blib-blab from other ways of figuring such a number. The whole "X" system for Hybrid cannons was started by Mark Jackson a former scenitist working for NASA's gaseous state combustion team. Here is his article concluding such research [<a href="http://www.spudfiles.com/spud_wiki/inde ... n">LINK</a>]

It isn't really rocket science here, drac's method seems simple enough and easy to follow. However I would like to try your technique pimp, but what exactly is the restriction size and "hybrid atomization pressure?"
