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

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.

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.

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.
