01(a) There are two reservoirs, A and B, with the water surface elevation in A 10 m higher than that in B. These are connected through two pipes in series with pipe 1 starting from A and pipe 2 ending in B. Lengths of both the pipes are 100 m, diameter of pipe 1 is 30 cm and diameter of pipe 2 is 25 cm. At the junction of these pipes, water is being withdrawn at the L v² D 2g rate of 0.02 m³/s. Friction loss in the pipes is given by h = f and the Darcy friction, f, entrance and at the junction, for both pipes is 0.02. Neglecting the head losses at the estimate the total water withdrawal from reservoir A.

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.

Water is drawn from an intake tower in Lake Ontario through a 3-km long precast reinforced concrete pipeline (Hazen-William’s C = 120) and delivered to the wet well of a low lift pumping station on shore which in turn supplies a water treatment plant. The pumping station is sized to deliver and will be operating at the maximum day flow rate of 2.65 m3/s. (a) If the design water elevation in the wet well is 70 m when the lake level is 74 m above MSL, determine the most economical pipe size for the intake (neglect local losses). (b) Compare the entrance and exit losses to the pipe friction losses to justify the assumption in (a). The entrance and exit loss coefficients can be assumed to be 1. (c) Sketch the hydraulic and energy grade lines. (d) Explain what would happen if the intake pipeline’s capacity was reduced but the pumping station is still operating at the same flow rate.
