Water Nozzle Design
Water Nozzle Design
(OP)
Hi everyone,
I'm currently in the process of designing a water nozzle with a set of parameters and I'm almost there but I was wondering if anyone had any materials that could further assist in design. I need to achieve 10.4 GPM minimum with only .44 psig on the inlet flowing to ambient. Best I can achieve right now is about 10 GPM. I've done all the mass flow and Bernoulli's calcs but theoretical and reality are off a bit. I'm 3D printing prototypes so not sure if the friction of the material is limiting flow. I was hoping to find more design information for nozzles like conical, parabolic, rao, astar, etc.
Anyone know of any good reference materials?
Thanks

In sensible units, assume a perfect design
>> v=sqrt(3033/500)
v = 2.4629 m/s
>> A=.0394/60/v
A = 2.6662e-004 m^2
>> r=sqrt(A/pi)
r = 0.0092124 m

Unfortunately I'm limited to my bore size to about .609". I was trying to speed up flow rate using nozzle principles

If there are any surface lines from your AM build you need to polish them out.
Solvent washing might work best, but it will change some dimensions.

RE: Water Nozzle Design
increasing the delta p to 0.79psi you just about get there
doesn't that suggest a solution ? (increase your vacuum alittle)
I expect the answer is "no".
So with a limited pressure, limited pipe diameter, there's only so much you can get in the best of all worlds (with a Cd of 1).
and this looks to be less than your 10.4 goal.

I’m limited to a .609” bore due to my ball valve constraints. Im doing these tests with 3D printed material so I figured I’ll gain some with a stainless nozzle, however, my mating parts may rob me of flow with the mismatch transitions.
