Fire Water Pump Deisel Consumption of the Full.

[MechanicalGraduate]

Hello Everyone,

I have a question about the fuel consumption of the tank for a Fire Water Pump Package.

According to NFPA-20 is it required 8Hr Full operation. However, Client is requiring 12Hr as minimum.

I know the capacity of the Tank 550 Gallons, Is there any way that I can work out whether or not those 550 Gallons are sufficient to guarantee the

12Hr full operation of the package?. I have ask the Vendor but they seem not to be sure.

Anyone can give me an Idea?.

Thanks you all and Regards,

Graduate Mech.

The driver equipment data sheet should provide you with a GPM or GPH rate at a given efficiency (generally 90% per the data sheets I've reviewed) at the engine's rated brake horsepower. With this information you should be able to accurately estimate a fuel demand for a 12 hour load duration.

I have never seen a diesel tank sized for a 12 hour run duration (or maybe I did, but did not realize it). 8 hours is the norm as you note. Why would you need such a long duration? What is the occupancy/fire loading. just curious.

might be an insurance thing or fuel delivary problem thing

or a critical building, that wants a little extra cushion

If the fire is still burning after 8 hours of full fire flow, I would think the fat lady has sung. There are no insurance companies I am aware of that ask for more than 8 hours.
