For the given sources and loads shown in the figure (planar view, all nodes at the same

elevation), find (a) the water flow distribution in each pipeline (present the values in the

figure below next to each pipeline), and (b) the pressure at the load points (C and E) if the

pressure at the source point A is 60 psi? Assume f-0.012 in all pipes. For convergence,

make sure the absolute maximum relative error defined as

2x (10.1.3

x 100%

should be less than 10%, where QNM is the flowrate running in the pipe from node N to M

at ith iteration.

Note: To show your independent work, choose values of initial flowrates (Os) different

from those who you work together with.

Present step-by-step details of your calculation clearly.

If any computer programs (MatLab, R, Excel, etc.) are used, turn in the program scripts or

worksheets, together with your solutions.
