Question
Text Book Problem 7.82 (page 261) Consider the total head-loss in the system for
this flow is 18.56 ft (head-losses in first and second pipe are 13.83 ft and 4.73 ft
respectively). Please show numerical values for EGL/HGL at the beginning/end/intermediate
change point. (Point distribution: elevation determination 5 points, EGL, HGL lines 4
points).(I think we are just using the values provided for head losses to solve this problem)
