WebYou have 11 gpm from your source. The flow rate off the loop system or the single mainline system will be divided by the number of lateral if each lateral's water demand is equal. Do not use more than 80% of your total flow rate in the design. Example: .8 x 11 gpm is 9 gpm divide by 3 lateral is 3 gpm per lateral. Webing “enough” water is a determination of how much water should be made available for any given situation. The following definition of required fire flow will be used in this manual: the rate of water flow, at a residual pressure of 20 psi (138 kPa) and for a specified duration, that is necessary to control a major fire in a specific structure.
