- 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 a 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.
