All over the world fluids are carried in different ways such as open channels, pipe line, concrete pipes etc. Naturally the fluids are flowing through open channels like rivers, streams and others, but artificially we use pipe line system to carry fluids from one point to other point. When a fluid flows from one point to another inside a pipe there will be a head loss. This head loss is caused by the friction of the fluid with the inner surface of the pipe wall and turbulence of the fluid flow. This head loss and friction coefficient affected by a number of factors which include the size of the pipe, the internal roughness of the surface of the pipe, length of the pipe and also affected by nature of fluids. Present work is to know the variation of friction coefficient for Galvanized Iron (GI) and Un-plasticized Poly Vinyl Chloride (UPVC) pipe materials for different quality of fluids using Darcy Weisbach equation.
