Wouldn't the relieving rate be attributed to steam in this case?
The purpose of the PSV would be for potential steam buildup in case of a fire, right?

Don't over think this.
But why are you relieving fire water? NFPA doesn't like this.

Mn3/hr is the equivalent flow at standard conditions of 0 Deg C(liquid).
If your fire water is at a different temperation, you can correct it, but likely an extremely minor correction.
Use of relief valve in the pump discharge is concerning, considering the possibilty of valve failure.

Don't mess with fire water systems.
They are not normal, but the work of the devil (aka NFPA). IMHO.
Find something more useful to work on.

Couldn't agree more. Every single time I got into design a fire water system, I was riddled with all the nonsense in that "industry".

Yes, the units are the same, but you need to correct for temperature and pressure, otherwise, you'll be using the wrong value.

Why would you need to correct for temperature and pressure since it is liquid in which case compressibility is negligible? If at all, might expect discrepancies but not much?
