2. The interval of points 1 and 2 of a main pipeline is composed of 2 km long, 40 cm diameter, and 1.5 km long, 30 cm diameter cast-iron pipe. Point 1 is 10 m higher than point 2. The pressure at point 2 is 5 kg per square cm higher than at point 1. The head loss due to contraction is 25% of the velocity head and that of enlargement is 10% of the velocity head before the change in cross-section towards the direction of flow. (a) Compute the velocity and discharge of the main pipeline. (b) Draw the hydraulic and energy grade lines. Use f= 0.022 for Darcy-Weisbach formula.
