New Criteria for Fire Protection of Large Air Force Warehouses. Volume II. Friction Loss in Pipes: Minimization by the Use of Chemical Additives

Abstract

Water additive solutions were tested for relative effectiveness in reducing friction loss in turbulent flow. Polyox FRA and Separan AP 273 were judged superior in performance in comparison of five candidate additives. A maximum increase of 2.5 in flow rate factor was attained in a simple gravity fed system. A subsequent test of Polyox FRA in a simulated sprinkler system showed no significant change in flow. This failure is believed to be due to faulty mixing. Methods to overcome this experimental difficulty are recommended.
