<![CDATA[Flowing water by pipe is mostly used to distribute the water from itssources to taps for various needs. On the way of distribution, it meets some obstacles,i.e.: velocity, surface and roughness changing. Thus, the research has been done inorder to know the influences of all the changes of the head loss on the 1 meter pipe.This research used Fluid Friction Apparatus complete with hydraulic bench andmanometer. Variation of flowing on pipe has done for 50 times, using each 6 mm and10 mm and four 17.5 mm pipe with different roughness which consist of differentsands diameter.From that research we found out that there’s a similarity in velocity and roughnesswith head loss showing polynomial order 2 ( hf = a + bu + cu2 and hf = a + bk + ck2 )where much velocity and roughness causing higher head loss. While pipe surfaceinverse proportional to head loss that shows exponential relationship (hf = a e –bA)where more surface causing less head loss.]]>
