19. Determine the flow into reservoir B in the pipe system shown. Use Manning's formula. (Neglect head loss due to contraction and enlargement) n = 0.01 1 EL 100 EL 50 WS 450mmm . 600 mm mm 9 350m Ly : 300m B Ly : 300m A. 33.55 L/s C. 434 L/s B. 101 L/s D. None of the Above 20. Based on the problem no. 19, determine the Head Loss A. 35m C. 22m B. 50m D. 13.25 m 21. If the head loss in a given length of uniform pipe is measured at different values of the velocity, it will be found that, as long as the velocity is low enough, the head loss, due to friction , will be directly proportional to the velocity. What kind of flow is this? A. Turbulent Flow C. Critical Flow B. Laminar Flow D. None of the Above. 22. An oil ( sg = 0.85. v = 1.8 x 10 5m2/s) flows in a 10cm diameter pipe at 500 cm/s. Is the flow laminar or turbulent? A. Turbulent C. Critical Flow B. Laminar D. None of the Above
