Refer to Figure 7.14. Assume that the head loss in the pipes is given by h_L = 0.02(L/D)(V ²/2g), where V is the mean velocity in the pipe, D is the pipe diameter, and L is the pipe length. The water surface elevations of the upper and lower reservoirs are 100 m and 60 m, respectively. The respective dimensions for upstream and downstream pipes are D_u = 32 cm, L_u = 190 m, D_d = 12 cm, and L_d = 110 m. Determine the discharge of water in the system.
