A pipe system transmits water at 20 °C from a tank 1 to tank 2 as shown. The pipe head loss coefficients are fl = 0.025 for the bigger diameter pipe and f2 = 0.035 for the smaller diameter pipe. The loss coefficient in each bend is K, = 0.4, the 100 m loss in the pipe entrance is K. = 0.5 and the loss in the contraction Ke = 0.3. Neglect the losses at the smaller pipe exit. All pipes are made of galvanized iron. i) - Elevation = 140 m Elevation = 105 m Water y= 250 m 4=100 m D-20cm Elevation l-Elevation = 95 m Tank 1 q- 15cm Determine the flow rate in the pipes? State your assumptions and justify if Elevation = 40 m Elevation = 35 m - Elevation = 30 m necessary. If the exit of the smaller pipe is located at the bottom of Tank 2 (i.e elevation = 30 m), do you think the flow rate will remain the same? Explain. Are there any vacuum regions in the pipe system? If yes, indicate them. ii) Tank 2 iii)
