Water flows steadily through a curved duct that turns the flow through angle @= 135º, 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 m’ at the outlet. The average velocity at the duct inlet is V1 = 6 m/s. The momentum flux correction factor may be taken as B1 = 1.01 at the duct inlet and B2 = 1.03 at the its outlet. The...
