Part 3 Agree or disagree Your boss suggests that friction losses in the straight pipe sections are negligible compared to losses in the threaded elbows and fittings of the system. What is the ratio of major head losses to total head loss (%)? i % Do you agree that friction losses in the straight pipe sections are negligible compared to losses in the threaded elbows and fittings of the system within the accuracy of the calculations? Determine Major head loss Water flows steadily through the 1.0-in.-diameter galvanized iron pipe system shown in the Video and in the figure below at a rate of Q=0.01 cfs.
