Nozzle Tip Discharge
Nozzle Tip Discharge
(OP)
Does nozzle tip discharge considered open-end discharge?
If so, it will solve all my problems.
Here is my situation:
I have a 1-1/2" water line coming in with 65psi. I want to plumb from the in-coming water line to a series of nozzles.
My target is to spray 67gpm at 60psi at the nozzle tip. How do I know if I have enough GPM at the incoming water line?
Can I consider nozzle tip to be an open-end discharge? So that I could use the Pressure Loss--Flow Chart. Or should I consider nozzle tip at a pressure of 60psi? Then how to calculate the GPM?

RE: Nozzle Tip Discharge
Sprinklers and nozzles can generally be simulated using,
Q = Cd * D2 * P1/2
Cd is around 0.97
P is a constant pressure to be held at the pipe end; the upstream side of the nozzle.
The pipe itself can be sized using any appropriate flow:head loss formula.
