39700/EEN 31000 Homework 07 Name: Johnson, Perri NN: 35 Page 3 H07.3 Water flows from a two-dimensional open channel and is diverted by an inclined plate as illustrated in the figure. What is the force exerted by the water at section (1)? At section (1) the pressure distribution is hydrostatic. Section (1) 10 tUs ft 20° Plate Governing Equation Solution: 1.0 ft Section (2) The velocity at section (1) is 10 f/s, what is the velocity at section (2)? The fluid acts as a free jet at section (2) overning Equation Solution: What is the horizontal force (per unit width) required to hold the plate in position? Neglect friction. Governing Equation: a 4
