As shown in Figure 3, a pipe of diameter d = 350 mm is transferring water from a river (freesurface 1) up the river bank to reach an irrigation channel with a free surface labeled 2. Thelevels of the free surfaces are kept as shown throughout the irrigation process. Given thatthe height difference between 1 and 2 is H = 3 m; the outlet of the pipe at point C is fullyimmersed under free surface 2; the friction factor f of the pipe is 0.04; length of pipe sectionAB is 15 m with head loss coefficient K = 6 for the entrance; length of pipe section BC is20 m with head loss coefficient K = 1.3 for the exit; distance from point B to level of freesurface 1 is h = 4m. (a) Do you expect this construction of the pipe system to successfully draw water fromthe river for irrigation? Explain your answer. (1) (b) Determine Q in the irrigation pipe system.10 (c) Determine the pressure at point B. (5) (d) If the saturated vapor pressure is -98.7 kPa, will cavitation occur at point B? (1)
