I don't know of any generic figures to use. I would assume you have some idea of the HP required for a given fire pump application. Review a number of different manufacturer's engine options to arrive at a ballpark figure. It is not that significant of a range, maybe 5-10 gpm on the low end to 30+ of the high end. Working on the industrial side, I haven't typically tried to cut tank sizing that close to worry about diesel cooling water consumption. If you actually have an incident that uses an entire tank water supply, will the loss expectancy be any different if the supply is depleted a few minutes earlier - I would tend to doubt it. I'm actually more concerned with the growing pump size of fire apparatus, particularly municipal pumpers where 2000 gpm pumps (or larger) are becoming quite common (and fire apparatus pumps are fairly conservatively rated). Luckily the fire service hasn't entirely figured out that you have to supply that large pump with adequately sized and number of supply lines. Nonetheless, the FD can pump some significant water and I often look at the impact of FD use beyond typical hose stream allowances when sizing water supplies, especially when large volume deluge systems are involved.
