This document contains notes for a water resource engineering class. It defines different types of fluid flows, including: - Steady and unsteady flows - Uniform and non-uniform flows - Laminar and turbulent flows - Compressible and incompressible flows - Rotational and irrotational flows - One, two, and three dimensional flows It provides descriptions and examples of each type of flow. For example, it states that steady flow is when fluid characteristics do not change over time, while unsteady flow is when they do change over time.

2. (a) Write a note on Uniform &
Non-uniform flow and Steady &
Unsteady flow.
(b) State classification of flow
profile with neat sketches if
required:
Mild slope, steep slope and
horizontal slope.

3.  Types Of Fluid Flow:-
1) Steady & Unsteady Flows.
2) Uniform & Non-uniform Flows.
3) Laminar & Turbulent Flows.
4) Compressible & Incompressible Flows.
5) Rotational & Irrotational Flows.
6) One , Two & Three Dimensional
Flows.

4.  Steady & Unsteady Flows:-
 Steady Flows:-
In which the fluid Characteristics Like
velocity, pressure, density , etc.At a Point do
not change with time.

5.  Unsteady Flow:-
In which the fluid velocity , pressure
or density at a point changes with
respect to time.

6. Uniform & Non-
uniformFlow :-
Uniform Flow:-
In which the velocity at
given time does not
change with respect to
space ( length of
direction of the flow ).

7.  Non-Uniform Flow:-
In which the velocity
at any time changes
with respect to space.
Changing in space

8.  Laminar & Turbulent flows:-
 Laminar Flow:-
 in which the
fluid particles move
along well defined
paths or stream
line.
Fig. Laminar Flow

9. Turbulent Flow:-
fluid moves in very irregular paths or zig –
zag Way.
velocity at a point fluctuates.

10. Compressible & Incompressible Flows:-
Compressible Flows:-
In which the density of the fluid changes
from point to point.
The density is not constant for the fluid.
Incompressible Flows:-
In which the density of fluid changes from point to
point.
 the density is constant for the fluid.

11. Rotational & Irrotational Flows:-
Rotational Flow :-
In which the fluid particles while
flowing along stream lines, Also rotate
about their own axis.
 Irrotational Flow:-
In which the fluid particles while
flowing along stream lines, do not
rotate about their own axis.

12. One Dimensional Flow:-
One , Two & Three Dimensional Flows:-
In which the flow parameter
such as velocity is a function of
time and
one space co-ordinate only.

13. Two Dimensional Flow:-
In which the velocity is a
function of time and
two rectangular space
co-ordinates.

14. Three Dimensional Flow:-
In which the velocity is the function of
time and
Three mutually perpendicular directions.
