Which of the following statements is/are correct with reference to non-uniform and steady flow in open channels?
1
The analysis of Hydraulic jump, formed in horizontal and frictional less channels which is the type of rapid varied and steady flow, is based on energy conservation.
2
The analysis of Hydraulic jump, formed in horizontal and frictional less channels which is the type of rapid varied and steady flow, is based on liner momentum conservation.
3
The differential equation of gradually varied flow is based on the assumption that pressure distribution is hydrostatic.
4
The differential equation of gradually varied flow is based on the assumption that the specific energy is remains constant
