Extracted text: 315 PROBLEM: Pipes 1, 2, and 3, having diameters of 150 mm, 200 mm, and 250 mm, and leading from reservoifs A, B, and C, respectively, join at a common point. All pipes are new cast iron and each is 300 m long. If the water level in reservoir C is 2 m higher than that in A and 5 m higher than that in B, determine the discharge and direction of flow in pipe 1. Use f = 0.02 for all pipes. 2,0m L-300 m D= 250 mm 5.0m L 300 m D 150 mm 2 B. Solution: 0.0826 fLQ? L 300 m D- 200 mm DS
