Question

The water jet separates from the round-ended energy breaker at an angle of 45 degrees and hits the rock wall at an angle of 20 degrees. It is known that the flow in the rectangular cross-section (1) is 3.5 and 6.5 m / s, with the order of Froude number and average velocity. Taking the specific gravity of the water as 10 kN / m3 and neglecting by using centrifugal force,
a) The total dynamic force acting on the energy breaker with a height of 1.5 m,

b) Determine the horizontal dynamic force acting on the rock wall.
