Water at 20°C is to be siphoned through a tube 1 m long and 2 mm
in diameter as shown in the figure below. For water at 20°C, take
ρ = 998 kg/m3 and μ = 0.001 kg/m⋅s.
Take π = 22/7. The kinetic energy correction factor
α is 2.0. What is the flow rate if H = 41 cm? Round the
answer to four decimal places. 


Problem 3: The following data were obtained for flow of 20°C water at 20 m/hr through a badly corroded 5-cm-diameter pipe which slopes downward at an angle of 8°: pı -420 kPa, zi -12 m, p2- 250 kPa, z2- 3 m. Estimate (a) the roughness ratio of the pipe; and (b) the percent change in head loss if the pipe were smooth and the flow rate the same. For water at 20°C, take ρ-998 kg/m3 and μ-0.001 kg/m s

Water is siphoned from a large tank and discharges into the
atmosphere through a 2-in.-diameter tube as shown in the figure
below. The end of the tube is 3 ft below the tank bottom, and
viscous effects are negligible. Determine the volume flowrate from
the tank. Determine the maximum height, H, over which the water can
be siphoned without cavitation occurring. Atmospheric pressure is
14.7 psia, and the water vapor pressure is 0.26 psia
