[3] Three-reservoir problem (P 4.3.2)Ignore minor losses and assume complete turbulence. (1) Determine flow rates in the branching pipe system depicted in figure, given the following water surface (WS) elevation

and pipe data(lengths and diameters): WS1 = 5200 ft L1 = 4000 ft D1 = 3 ft WS2= 5170 ft L2 = 2000 ft D2 = 5 ft WS3 = 5100 ft L3 = 3000 ft D3 = 4 ft All pipes are lined ductile iron (e= 0.0004 ft.)and the temperature of the water is 68°F. (2) Determine the elevation of the junction (J)if the pressure head (P/y) at the junction measured by a piezometer (height from J to Hj) is 30 ft.
