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....
