A 4.2 K-factor sprinkler must deliver 17 gpm (692 mm/min). What pressure is required?

Show Suggested Answer Hide Answer
Suggested Answer: B

To deliver 17 gpm with a 4.2 K-factor sprinkler, approximately 9.22 psi pressure is required. This is calculated using the sprinkler's K-factor formula, which relates flow rate, pressure, and the K-factor.

A) 4.52 psi (0.31 bar) is the way to go. I can already feel the water pressure coursing through my veins. Bring on the next question!

Hmm, I'm gonna go with D) 36.86 psi (2.54 bar). Bigger is better, right? Just like my ego after acing this exam.

I agree with Paris, because the formula for pressure is flow rate divided by K-factor

C) 16.38 psi (1.13 bar) seems like the correct answer. The K-factor and flow rate are given, so we can plug those into the formula to solve for the pressure.

So, for this problem, it would be 4.2 multiplied by the square root of 17.
