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.

I thought it would be lower, maybe option A?

Wait, 65 gpm at 14.9 psi? That sounds off to me.

The K-factor is usually calculated based on flow rate and pressure.

I vaguely recall that higher flow rates usually mean higher K-factors, so maybe it's C or D, but I can't remember the specifics.

I feel like I might be mixing up the K-factor values. Wasn't there a formula we used that involved both gpm and psi?

I practiced a similar question last week, and I think the K-factor was around 11 or 12 for similar flow rates. Maybe it's B?

I think I remember the K-factor being related to flow rate and pressure, but I'm not sure how to calculate it exactly for this question.

Wait, what's the K-factor again? I'm a little fuzzy on that concept. Maybe I should review my notes before trying to solve this.

No problem, I got this. The K-factor is just a function of the flow rate and pressure drop, so I'll crunch the numbers and pick the right answer.

Hmm, this looks like a fluid mechanics problem. I'll need to remember the K-factor formula and plug in the given values to solve this.
