Water enters a reach of rectangular channel where y1 = 0.5 m, b = 7.5 m, and Q = 20 m3 /s (Fig. P10.39). It is desired that a hydraulic jump occur upstream (location 2) of the sill and on the sill critical conditions exist (location 3). Other than across the jump, losses can be neglected. Determine the following:
(a) Depths at locations 2 and 3
(b) Required height of the sill, h
(c) Resultant force acting on the sill
(d) Sketch the water surface and energy grade line.
(e) Describe the nature and character of the jump
