Types of fluid flows

Let us discuss them one by one.

Flows are broadly classified into the following three categories.

-      Laminar Flow

-      Turbulent Flow

-      Transient Flow


                 In case of pipes.
           If Reynold’s No.  ≤ 2000.    The flow will be laminar.

           If Reynold’s No.  > 2000.    The flow will be Turbulent.

               In case of channels.

 If Reynold’s No.  ≤ 500       The flow will be laminar.

 If Reynold’s No.  > 500.      The flow will be Turbulent.

TYPES OF FLOW W.R.T DISTANCE (between two sections):


TYPES OF FLOW W.R.T TO TIME:



TYPES OF FLOW W.R.T TO DENSITY:



           DIFFERENCE:

                Difference between uniform and steady flow is that uniform flow is between two sections

                 while steady flow is at a particular section.
