Ten identical pipes connect an upstream reservoir A (water elevation 95 m) to a downstream reservoir B (water elevation 70 m). The elevations of the pipe nodes are given by dashed contour lines with the contour elevations indicated (in metres). Each pipe has a 250 mm diameter, is 200 m long and has a 'C' value of 130.
a) Determine the total flow through this pipe system.
b) Determine the maximum and minimum pressure head in the system.
c) Which branch conveys the highest flow: Branch P1-P2-P4-P5-P8 or Branch P3-P6-P7-P9? Why?
