A wide channel is 1 m deep and has a velocity of flow, V, as 2.13 m/s. If a disturbance is caused, an elementary wave can travel upstream with a velocity of
-
- 1.00 m/s
- 2.13 m/s
- 3.13 m/s
- 5.26 m/s
Correct Option: A
Celerity of wave, C = √gy , = √9.81 × 1 = 3.13 m/s
Vm & V1 are in opposite directions
∴ C = Vw + V1
3.13 = Vw + 2.13
∴ Vw = 1 m/s
