Classification of Flow

4 classifications of flow

1.Steady uniform flow
example: pipe with  constant D and Q
example: channel with constant A and Q

2.Steady non-uniform flow 
example: pipe with different D and constant Q
example: channel with different A and constant Q

3.Unsteady uniform flow
example: pipe with constant D and different Q
example: channel with constant A and different Q

4.Unsteady non-uniform flow
example: pipe with different D and Q
example; channel with different A and Q
