What K-factor would result with 65 gpm (246 lpm) flowing at 14.9 psi (1.03 bar)?

Show Suggested Answer Hide Answer
Suggested Answer: B

With 65 gpm flowing at 14.9 psi, a K-factor of approximately 11.2 (160) can be deduced using the K-factor formula, which relates flow, pressure, and the K-factor in sprinkler system calculations.

Alright, time to put on my thinking cap. I'm gonna go with C) 16.8 (240) - it just feels right, you know? Plus, it's a nice round number, which is always a good sign.
