Wait, is the Hazen-Williams equation a secret trick question or something? Seems too obvious to be the right answer.

Bernoulli calculation? That's a new one on me. Maybe the exam writers are trying to trick us with obscure options.

Yeah, it seems like a tricky option compared to the other more common methods.

I think Bernoulli calculation is not commonly used in determining rate of fire flow.

Hmm, I'm not sure. Maybe we should review the material again before the exam.

Sprinkler calculations? Nah, that's a different topic altogether. This is about the basic methods for determining fire flow, not sprinkler design.

The Venturi principle? Really? I don't think that's used for fire flow calculations. Sounds more like something from a physics lab.

Yes, the Royer/Nelson method is another important calculation method for rate of fire flow.

I believe C) Sprinkler calculations is also one of the basic methods used.

Hmm, I'm pretty sure the third calculation method is the Hazen-Williams equation. That's the one we covered in my fire protection class.

So the other two methods are the Royer/Nelson and US National Fire Academy, right?
