Explanation Draw the diagram to show the direction of the water flow. Figure-(1) Write the expression for the velocity of the upstream flow. V 1 = V + V w (I) Here, the water flow velocity in the channel is V and the wave upstream velocity is V w . Write the expression for the depth ratio. y 2 y 1 = V 1 V 2 (II) Here, the upstream water depth is y 1 and the downstream water depth is y 2 . Write the expression for the Froude number. F r 1 = V 1 g y 1 (III) Here, the acceleration due to gravity is g and the flow depth before the jump is y 1 . Write the expression for the flow depth after the jump. y 2 y 1 = 1 2 ( − 1 + 1 + 8 F r 1 2 ) (IV) Conclusion: Substitute 6 m / s for V and 2 m / s for V w in Equation (I). V 1 = 6 m / s + 2 m / s = 8 m / s Substitute 8 m / s for V 1 and 2 m / s for V 2 in Equation (II)
