Firefighting Water - Required Volume Flow

Required water for firefighting.

Sponsored Links

Water demand for firefighting can be estimated as

Q = 1020 n1/2 (1 - 0.01 n1/2)                              (1)

where

Q = water demand (gpm)

n = population of people (in thousands)

  • 1 US gal/min (gpm) = 0.227 m3/h
