Vent Water flows from a container as shown in the figure. The pipes have a diameter D = 5 cm. Viscosity of water: = 1 mPa.s. hy h = 3 m, h2 = 2 m, a = 6 m, h = 20 cm. h2 hy a) Ignore all losses and calculate the velocity of the outflowing water with the Bernoulli equation. b) Is the flow of the water for this velocity turbulent or laminar? c) Now calculate the velocity once again including all the losses. minor: inlet: Kin = 0.1, elbows: Kelb = 0.2, valve: Kval = 0.4, outlet: Kout = 0.1, major: the material of the pipes is galvanized iron. Draw lines in the moody diagram that indicate how you found your value for X. d) Calculate the height he of the fountain. 0.1 TUISTE 0.09 Critical Laminar Lone Transition 0.08 flow zone HU Nu + Completely turbulent regime 0:05 0.07 64 Re 0.04 0.06 0.03 0,05 0.02 0.015 0.04 0.01 0.00 Reenit 0.006 0.03 0,004 f (note: f = ) 0.023 0.002 0.02 0.001 0.0008 0.0006 0.0004 0.015 0.0002 (ft) -0.01 0,001-0,01 -0.001 0.00085 0.0005 0.00015 0.000005 Riveted steel Concrete Wood Cast iron Galvanized iron Wrought iron Drawn tubing e (mm) 3 0.3.3 0.3 0.26 0.13 0.046 0.0001 Smooth pipes 0.0005 0.01 0.000.001 LENNE 0.0015 0.000,005 0.009 0.000,01 0.008 79 102 2 2 3 4 5 6 7 9 101 2 3 4 5 6 7 9 5 2 3 4 5 67 9 3 4 5 107 2 3 4 5 6 7 9 2 3 4 5 6 7 9 3 4 6 106 Reynolds number Re 105 108
