Water flows steadily through a curved duct that turns the flow through angle = 135 degrees, as shown in Fig. 3. The cross-sectional area of the duct changes from A1 = 0.025 m2 at the inlet to A2 = 0.05 m2 at the outlet. The average velocity at the duct inlet is V1 = 6 m/s. The momentum flux correction factor may be taken as 1 = 1.01 at the duct inlet and 2 = 1.03 at the its outlet....

Consider a venturi with a small hole drilled in the side of the throat. This hole is connected via a tube to a closed reservoir. The purpose of the venturi is to create a vacuum in the reservoir when the venturi is placed in an airstream. (The vacuum is defined as the pressure difference below the outside ambient pressure.) The venturi has a throat-to-inlet area ratio of 0.85. Calculate the maximum vacuum obtainable in the reservoir when the venturi is...
