An open channel is a conduit in which a liquid flows with a free surface. The free
surface is actually an interface between the moving liquid and an overlying fluid
medium and will have constant

Dimensional and Model Analysis
Introduction
Model analysis is carried out to predict the
performance of the hydraulic structures or machines

Dimensional Analysis
Introduction
It is a mathematical technique to solve several
engineering problems with the study of dimensions.
A physical phenomenon can be expressed in terms of
governing equations consisting number of variables.

Numerical 1
A fluid has an absolute viscosity of 0.048 Pas and a
specific gravity of 0.913. For the flow of such a fluid over
a flat solid surface, the velocity at a point 75 mm away
from the surface is 1.125 m/s. Calculate the

Properties of Fluids
Introduction
Fluid is substance which is capable of flowing
It has no definite shape of its own, but confirms to the shape of
the containing vessel.
The difference that exists between solids and fluids is in their
relative abilitie

Fundamentals of Fluid Flow
Introduction
To study the behaviour of fluid in motion we need to
consider several factors.
Whereas, behaviour of fluid in rest is influenced by its
specific weight only.
The science of study which deals with fluid motion and
