Question

An open channel flow encounters a hydraulic jump as shown in the figure below.                          

 

The following fluid flow conditions are observed between A and B:

1. Critical depth
2. Steady non- uniform flow
3. Unsteady non- uniform flow
4. Steady uniform flow

The correct sequence of the flow- conditions in the direction of flow is

1. 1,2,3,4
2. 1,4,2,3
3. 2,1,4,3
4. 4,2,3,1
