The basic difference between flow in pipe and flow in open channel flow is the boundary conditions and the free surface of the liquid which is given below:
|
Open Channel Flow |
Pipe Flow |
|
Flows are characterised by a free surface open to the atmosphere. |
Top surface has pressure more than atmospheric |
|
Flow driven is by Gravity (potential energy). |
Flow is driven by Pressure. |
|
Flow cross section is unknown in advance because the flow depth is unknown. |
Flow cross section is Known/ fixed. |
|
Flow depth deduced simultaneously from solving both continuity and momentum equation |
Velocity deduced from continuity equation. |
|
Hydraulic Grade line (HGL) is coincides with top surface of flow. |
HGL is always above the top surface of flow. |
