Determine the flow in the pipes and the pressure head elevations at the junctions of the closed-loop horizontal pipe network illustrated, neglecting minor losses. All pipes have the same roughness height of 0.03 mm. The outflows at the junctions are shown in liters per second (see figure below). Water kinematic viscosity is 1*106 m/ sec. (Hint: Take an initial estimate of QAB= 120 liter/sec). At least perform two iterations. Pipe AB BC Length (m) 500 600 200 Diameter (mm) 200 150 Pressure head elevation at A = 60 m.
