Continuity and Conservation of Matter
1. Mass flow rate
If we want to measure the rate at which water is flowing along a pipe. A very simple
way of doing this is to catch all the water coming out of the pipe in a bucket over a
fixed time period. Measuring

1. Fluid Dynamics
Objectives
Introduce concepts necessary to analyse fluids in motion
Identify differences between Steady/unsteady uniform/non-uniform
compressible/incompressible flow
Demonstrate streamlines and stream tubes
Introduce the Continuity p

Fluids Mechanics and Fluid Properties
What is fluid mechanics? As its name suggests it is the branch of applied mechanics
concerned with the statics and dynamics of fluids - both liquids and gases. The
analysis of the behaviour of fluids is based on the f

Forces in Static Fluids
This section will study the forces acting on or generated by fluids at rest.
Objectives
Introduce the concept of pressure;
Prove it has a unique value at any particular elevation;
Show how it varies with depth according to the h

Forces on Submerged Surfaces in Static
Fluids
We have seen the following features of statics fluids
Hydrostatic vertical pressure distribution
Pressures at any equal depths in a continuous fluid are equal
Pressure at a point acts equally in all directi

Pressure Measurement By Manometer
The relationship between pressure and head is used to measure pressure with a manometer (also know as a liquid
gauge).
Objective:
To demonstrate the analysis and use of various types of manometers for pressure measuremen

Properties of Fluids
The properties outlines below are general properties of fluids which are of interest in
engineering. The symbol usually used to represent the property is specified together
with some typical values in SI units for common fluids. Value

The Bernoulli equation
1. Work and energy
We know that if we drop a ball it accelerates downward with an
acceleration
(neglecting the frictional resistance due to air). We can
calculate the speed of the ball after falling a distance h by the formula
(a
=

Dimensional Analysis
In engineering the application of fluid mechanics in designs make much of the use of
empirical results from a lot of experiments. This data is often difficult to present in a
readable form. Even from graphs it may be difficult to inte

Applications of the Bernoulli Equation
The Bernoulli equation can be applied to a great many situations not just the pipe flow
we have been considering up to now. In the following sections we will see some
examples of its application to flow measurement f

The Momentum Equation And Its
Applications
We have all seen moving fluids exerting forces. The lift force on an aircraft is exerted
by the air moving over the wing. A jet of water from a hose exerts a force on whatever
it hits. In fluid mechanics the anal
