75 psi? That seems excessive for a rack storage!
AN

Totally agree, 35 psi makes sense here.

Wait, are we sure it's not 52 psi? Seems high.

Definitely B, can't go lower with Class IV.

Minimum is 35 psi for that setup!

I’m leaning towards 75 psi since it seems like a safe bet for high storage, but I wish I had reviewed this topic more thoroughly.

I remember something about needing at least 52 psi for certain configurations, especially with double-row racks. Could that be the answer?

I practiced a similar question about ESFR systems, and I feel like 35 psi might be the right choice, but I’m not completely sure.

I think the minimum operating design pressure for ESFR sprinklers is usually higher for Class IV commodities, but I can't remember the exact number.

Alright, time to put my problem-solving skills to the test. I'll start by breaking down each component of the question and then work through the calculations methodically.

This is right in my wheelhouse! I've got the NFPA standards memorized, so I should be able to quickly calculate the minimum operating design pressure based on the given details.

Ugh, I'm not sure I fully understand all the terminology in this question. ESFR spunkier? Rack storage? I'm going to have to review my notes carefully before attempting this.

Okay, let's see. The key information seems to be the K-factor of the ESFR spunkier, the storage height, and the building height. I think I can work through this step-by-step to find the right answer.

Hmm, this looks like a pretty technical question. I'll need to carefully review the details about the ESFR spunkier, rack storage, and building height to determine the minimum operating design pressure.

Ah, the joys of fire protection engineering questions. It's like a treasure hunt, but instead of finding buried treasure, you get to find the right pressure value. Exciting stuff!

I see your point, but I still think A) 20 psi (1.4 bar) makes more sense based on the design pressure requirements
TA

I disagree, I believe the correct answer is C) 52 psi (3.6 bar)

Hmm, I think I remember learning about this in my fire protection class. Time to dust off the old textbook and see if I can figure out the right answer.

Actually, I think it's 75 psi (5.2 bar)
MA

No, I believe it's 35 psi (2.4 bar)

I think the minimum operating design pressure is 52 psi (3.6 bar)

I think the answer is A) 20 psi (1.4 bar)

Okay, let's see. 20 ft high storage in a 35 ft building? That sounds like a pretty standard setup. But all these pressure values... I'm going to have to break out the calculator for this one.
LO
Lorita

That seems more reasonable for the design pressure.
LU

B) 35 psi (2.4 bar)
KR

Hmm, I think it might be higher than that.

Wait, what? ESFR spunkier? Is that some kind of new-age fire suppression system I'm unaware of? I feel like I need a translator just to understand this question.
