Chapter 0 – Problem 0.14

0.14 Suppose the pipeline described in the previous questions has five 90° bends along its 300 m length, each with a minor loss coefficient of 0.1. Compute the total minor loss associated with all five bends. How significant is this minor loss compared to the uncertainty in the pressure values at the end of pipeline due to the potential variation in the estimated Hazen-William roughness coefficient? At what flow velocity does the minor loss becomes significant compared to the variation in pressure head associated with the uncertainty in the roughness coefficient

[Answer: Total minor loss = 0.102 m]
