The speed of the waves will travel towards upwards and downward stream and Froude number
Explanation of Solution
Given:
Velocity of river flow
Depth of water flow in the river
Calculation:
Calculate the speed of surface wave
Calculate the velocity in upstream stream direction
Here, the velocity of waves independent of the river is
Thus, the velocity of wave in the upstream direction is
Calculate the velocity in downstream stream direction
Thus, the velocity of wave in the downstream direction is
Calculate the Froude number
Thus, the Froude number of the flow is
