3. i.introduction
Velocity — The speed with which knowledge moves
through an organization.
Viscosity — The richness or thickness of the knowledge
transferred.
Laminar flow is defined as that type of flow in which
the fluid particles move along well defined paths or
stream line and all the stream lines are straight and
parallel this type of flow is known as laminar flow
Turbulent flow is defined as that type of flow in which
the fluid particles move is a zig-zag way. The fluid
particles crosses the paths of each other is known as
turbulent flow

8. iv.APPARATUS
The apparatus consist of
a. A tank of water
b.A small tank containing some day
c. A glass tube having a bell mounted entrance at one end and regulating
valve other ends

9. v.Observation by Reynolds
1.At low velocity, the dye will
move in a line parallel to the
tube and also it does not get
dispersed.
2.At velocity little more than
before the dye moves in a wave
form.
3.At more velocity the dye will no
longer move in a straight-line.

10. vi.Types Of Flows Based On Reynold Number
If Reynold number, RN < 2000 the flow is
laminar flow.
If Reynold number, RN > 4000 the flow is
turbulent flow.
If Reynold number i.e. 2000 < RN < 4000,we
observe a flow in which we can see both
laminar and turbulent flow to gather. This
flow is called Transition flow.
