Problem 26P
Repeat Prob. 14–26, but with a rough pipe—pipe roughness ε= 0.12 mm. Assume that a modified pump is used, such that the new pump operates at its free delivery conditions, just as in Prob. 14–26. Assume all other dimensions and parameters are the same as in that problem. Do your results agree with intuition? Explain
