Determine flow rates in the branching pipe system depicted in Figure P4.3.2 given the following water surface (WS) elevation and pipe data (lengths and diameters): ..

All of the pipes are lined ductile iron (DIP, e = 0.0004 ft), and the temperature of the water is 68 °F. Also determine the elevation of the junction (J) if the pressure head (P/y) at the junction measured by a piezometer (height from P to J) is 30 ft.
