In the three-reservoir system shown below, water flows from A to junction J at a flow rate Q1 = 0.70 m/sec. The reservoir/Node elevations and pipe information is shown below. Assuming a Hazen- Williams Coefficient (CHw) = 129 and ignoring all minor losses and the pressure head at node j ( Pj/y)= 62 Determine the flow rate in pipe 2 (Q2) Pipe Length (m) Diameter (m) 1 500 2 400 3 150 Reservoir/Node Elevation (m) 300 250 240 200 A BC 0.5 0.4 ???
