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.
