) For the overflow of ogee spillway as shown in fig. (1), determine the dynamic force on the curved surface. The head 1.5 m and upstream vertical face = 12 %3D

A partially open sluice gate discharges water into a rectangular channel. The tail water depth in the channel is 3m and Froude number is 1/2/2. If a free hydraulic jump is to be formed at downstream of the sluice gate after the vena contracta of the jet coming out from the sluice gate, the sluice gate opening should be (coefficient of contraction Cc = 0.9)

The channel is subjected to a shear of V = 20 kip. (a) Determine the shear flow at point A. 1.5 im (b) Determine the shear flow at point B. (c) Determine the maximum shear flow in the channel. 4 in. A 8 in. 1.5 in. B 13 in. 1.5 in.

In a 4.0 m wide rectangular channel (n=0.017) the bed slope is 0.0006. When thechannel is conveying 10.0 m³/s of flow, estimate the nature of GVF profiles at two far away sections P and R in this channel where the depth of flow is measure as 1.6 m and 2.1 m respectively
