But since friction head with turbulent (sprinkler) flow is proportional to the
velocity squared, and the data from Ron Greenman's link says 'K Value for use
in the formula hf=k(v^2/2g)', and the velocity varies as the

100 PSI, but since they move away from v^2, we cannot trust them. Thanks

I started to say before getting overly precise (but that horse has
left the barn), it might be helpful to keep in mind that the K valve
on a sprinkler is NOT a constant at different flows. It is an
AVERAGED result for flows from 7 psi to 100 psi.

Vince,
Vince,
I get K=149.
Instead of Q=K*P^2, I used Q=vA, (Q)cubic feet per second equals (v)feet per
second times (A)
square feet.
A=PI*radius^2,=PI*((2.5"/12/2)^2)=.034 ft^2. This is the "theoretical" area,
and we have to reduce
it proportional to the friction loss through the valve. For lack of a

Each K value that you want to obtain only use the formula.
Q=√(P)*K
K=Q/ √(P)K=250/√(100)
For the case of 1.5 hose.
Q=√(P)*K

Yup, PERMANACE. The thing has to be installed permanently so it has

Um, Ron? According to that chart a 2.5" angle valve will flow 9.9gpm at
100psi. I don't think that's quite in accordance with HW.
If you are flowing 250 through the valve at 100psi, it has a K of 25.0, no?
Vince,
