Luminar flow and turbulent of dilute polymer guar gum (fatter) solutions in smooth and in rough pineswas studied This experiment use in 25.4 mm of diameter pipe (PVC), which roughened by (k) 0, 34. 0,8and 1, 59 mm roughness value of sand grain and 250, 500 and 1000 ppm for additive concentration. Theresults show that flow properties ore influenced by polymer addition and surface roughness. In thetransition and turbulent flow regime without additive the increasing of friction coefficient appeared to beeffcted by wall condition alone. Addition of polymer to water is effective for rough pipe. For examplewith addition of 1000 ppm of polymer reduced drag in k/D = 0,03 rough pipe by 24 percent at Reynoldsnumber 2 x 10 , whereas in 250 ppm addition tested drag was reduced only 5 percent |
