Nitrous Jet Equation?! Whheeee!
Nitrous Jet Equation?! Whheeee! I am familar with jet size calculators that automatically do this but does anyone have the raw equation I could look at?
I have been scouring the internet and haven't found one I can just plug AFR, pressure, atmosphere pressure, and orifice size into!
The only thing I can think of is maybe to take a propellant equation and find out what mass of nitrous is coming out for given conditions and then maybe use chemistry to find out how much fuel I would need to react with that nitrous. That would take some work but sounds interesting.
Just talking anyways.
Anyone have any hints of what types of equations to take a gander at?

I have a flow rate calcutor based on orfice size and pressure differential. for example 1000psig subtract -0.7psig * cross sectional area * loss coeffiecent.
If you want it I can post up my notes.
You'll want to assume that there is no state change across the nozzle. In fact you want absoulutely no state change until it is in the engine.

That would be pretty neat if you could post something up.
I have tried putting a massive jet in like .080 in a fogger. It didn't seem to make alot of power. Probably because in liquid form the naturally inducted air guides it to where it needs to be?
