Example 10. 6 Uniform Flow, Variable Roughness Water flows along the drainage canal having the properties shown in Fig. E10.6a. If the bottom slope is S,= 1m/500m=0.002, estimate the flowrate 0.7 m - n3 = 0.030 nį = 0.020 (3) 0.2 m n2 = 0.015 0.25 m (2) 2/3 Quotal = Q1 + Q2+ Q3 = A¡V1 + A¸V2 + A3V3 Manning equation

It's just two step problem ,Please solve Correctly.

A Cipolletti weir, popular in irrigation systems, is trapezoidal,with sides sloped at 1:4 horizontal to vertical, as in Fig. The following are flow-rate values, from the U.S.Dept. of Agriculture, for a few different system parameters.   Use this data to correlate a Cipolletti weir formula with areasonably constant weir coefficient.

A circular jet of water impinges on a flat plate as shown in Figure P10.49. The water spreads out equally in all directions and at station 1, the flow is essentially uniform over the depth Y1. The jet exit velocity V is 10 m/s and the exit diameter D is 10 mm. If you are given that R = 8D, and Y1 = D/4 (a) Find the Froude number of the flow at station 1. (b) If you are given that a circular hydraulic jump forms near station 1, estimate the depth of water after the hydraulic jump using the one-dimensional hydraulic jump relationship. Under what conditions will the accuracy of this estimate improve?
