NFPA CWBSP Exam - Topic 2 Question 24 Discussion

Actual exam question for NFPA's CWBSP exam
Question #: 24
Topic #: 2
[All CWBSP Questions]

Annual testing for a 1,500 gpm (5,677 L/min) at 80 psi (1.4 bar) fire pump supporting an attached sprinkler system

demand of 1,800 gpm (6,813 L/min) at 100 psi (6.9 bar) is being conducted. The flow test of the fire pump must

achieve what minimum flow rate and discharge pressure?

Show Suggested Answer Hide Answer
Suggested Answer: C

For annual testing of fire pumps, NFPA standards require the pump to be tested at its rated capacity and pressure, as well as at 150% of its rated capacity at a correspondingly lower pressure. In this scenario, the minimum flow rate required for the test is the demand of the attached sprinkler system, which is 1,800 gpm at 100 psi, to ensure the pump can meet or exceed the system's highest demand.

I feel C is the only option that ensures proper pressure.

True, but A is too low for the demand. C is safer.

Agreed, C makes sense. It matches the sprinkler system's needs.

I think it should be C. We need to meet the demand.

2,250 gpm seems way too high for this setup!

C is correct, but I wonder if the pressure is really enough for all scenarios.

I thought it was supposed to be 1,500 gpm at 80 psi? This is confusing!

Definitely option C, that's the only one that matches the demand.

Imagine if the fire pump could shoot water high enough to water the moon! That would be one heck of a fire pump.

C is tempting, but the question specifically asks for the minimum flow rate and pressure, so A is the way to go.

Haha, D is just ridiculous. Who would need a fire pump that can pump 2,250 gpm at 65 psi? That's overkill!

I agree, A is the correct answer. Anything less than the system demand would be unacceptable.

The answer is clearly A. The fire pump needs to match the system demand, which is 1,500 gpm at 80 psi.

I’m a bit confused about the pressure requirements. Does the discharge pressure need to be at least 100 psi to support the system?

I practiced a similar question where the pump had to exceed the demand, so I feel like option C might be the right choice here.

I remember something about the minimum flow rate needing to be above the pump's capacity, but I'm not sure if it has to match the demand exactly.

Okay, I think I got this. The fire pump needs to match the demand of the sprinkler system, which is 1,800 gpm at 100 psi. So the minimum flow rate and discharge pressure it needs to achieve is that same 1,800 gpm at 100 psi. The answer is C.

Alright, let me break this down. The fire pump is 1,500 gpm at 80 psi, but the demand is 1,800 gpm at 100 psi. So the pump needs to meet or exceed that demand during the test. I think the answer is C, 1,800 gpm at 100 psi.

I think the fire pump needs to meet the demand of the sprinkler system, so it should be at least 1,800 gpm, right?

Hmm, this is tricky. I think the key is that the fire pump needs to match the demand, not exceed it. So the minimum flow rate and discharge pressure it needs to achieve is the 1,800 gpm at 100 psi. I'm pretty confident that C is the right answer.

I'm a bit confused. The question says the fire pump is 1,500 gpm at 80 psi, but the demand is 1,800 gpm at 100 psi. Does that mean the pump needs to exceed the demand, or just match it? I'm not sure which answer is correct.

Okay, let's think this through. The fire pump needs to support a demand of 1,800 gpm at 100 psi, so the minimum flow rate and discharge pressure it needs to achieve during the test must be that same 1,800 gpm at 100 psi. That means the answer is C.
