1. The problem statement, all variables and given/known data Using the Haaland equation shown below, determine the Reynold number Re Friction factor λ = 0.032mm = 0.000032m Absolute roughness Ks = 1.5 x 10-6m Internal bore diameter d= 0.04m 1/√ λ = -1.8log[(6.9/Re) + [(ks/d)/3.7]1.11] I have tried to solve the above equation but haven't got a clue as I have not been taught to this level. Consequently it's a bit unfair. Someone tried to help me but confused me even more. I do know the answer but need to show how I got the answer. Any help would be appreciated.
