The basic Differences between pipe flow and open channel Flow  are given below

 

Pipe Flow :

 

 

DIFFERENCES BETWEEN PIPE FLOW AND OPEN CHANNEL FLOW 1 DIFFERENCES BETWEEN PIPE FLOW AND OPEN CHANNEL FLOW 2

Open Channel Flow :

 

DIFFERENCES BETWEEN PIPE FLOW AND OPEN CHANNEL FLOW 3

 

No.OPEN CHANNEL  FLOWPIPE FLOW
1Flow occurs due to gravity .Flow occurs due to different in pressure .
2The maximum velocity occurs at a little distance below the water surface.The maximum velocity occur at the center of the pipe .
3.Cross section of open channel can be trapezoidal, triangular,rectangular ,circular etc.Cross section of pipe generally round .
4.HGL(Hydralic Gradient Line ) coincide with water surface line.HGL(Hydralic Gradient Line ) do not coincide top surface of the water

 

I just add four basic difference between pipe flow and open channel flow here . If you want to add some please ,post your comment below .

Thanks !
