3. Water is supplied to a town through a gravity main, 0.6m in diameter and 50 km long, across an undulating ground from the headworks to the service reservoir in the town. The pipe off-take at the headworks is at a reduced level (RL) +480 m and the maximum water level of the reservoir is at RL +380 m. The lowest ground level of the mains is at RL +280 m at a point 25 km from the take-off. It is desired to increase the current supply to the town by 30%. Determine the distance you would lay a duplicate pipe of the same diameter. State all assumptions made.
A Francis radial-flow hydroturbine is being designed with the following dimensions: r2 = 2.00 m, r1 = 1.42 m, b2 = 0.731 m, and b1 = 2.20 m. The runner rotates at n. = 180 rpm. The wicket gates turn the flow by angle ?2 = 30° from radial at the runner inlet, and the flow at the runner outlet is at angle ?1 = 10° from radial. The volume flow rate at design conditions is 340 m3 /s, and the gross head provided by the dam is Hgross = 90.0 m. For the preliminary design, irreversible losses are neglected. Using appropriate software, investigate the effect of the runner outlet angle ?1 on the required net head and the output power. Let the outlet angle vary from −20° to 20° in increments of 1°, and plot your results. Determine the minimum possible value of ?1 such that the flow does not violate the laws of thermodynamics.

Two reservoirs A and B is connected by a 250mm-dia. pipe which is 1000m long. Reservoir B is 8 meters below that of A. Other reservoirs C and D are also connected by a 300mm-dia. pipe, 2,200m long with reservoir D 10mbelow that of C and reservoir C is also 4m below that of A. In order to increase the quantity of water entering reservoir D, thetwo pipelines AB and CD are connected by a pipeline EF which is 1800m long which branches from the 250mm-dia. at a point E 400 meters from A and connects with the 300mm-dia. pipe at F 800 meters from reservoir D.a). Determine the quantity of water flowing towards B and D if 27 liters per second flow through pipe EF. Assume frictionfactor f to be 0.022 for all pipes. Consider only friction losses.b). Determine also the diameter of the pipe EF to carry 27 liters/sec.
