1) Introduction:
Energy is a property of objects and systems which are conserved by nature and is also
defined as the ability to do work. Energy can be expressed in many forms such as kinetic,
thermal and potential. An energy equation had to be developed that applies to all these
different forms of energy. For kinetic energy, the energy equation contains a lot of
variables that can create error which can be resolved by adding what is called the ‘kinetic
energy correction coefficient’ which has the symbol ‘α’.
The coefficient α is an important constant because it helps in calculating the true velocity
of the flow since the average velocity equation is not accurate. The reason that average
velocity is not accurate is that in the case of nonuniform velocity distribution, the
velocity head of an open channel flow is generally greater than the value computed by
using the average velocity. Therefore, the purpose of this lab is to calculate that
coefficient using readings taken from a leaf blower and the energy equation.
2) Procedures:
First of all, the ambient temperature of the lab was recorded to be 300 K.
In order to take dynamic pressure readings, a manometer and a pitotstatic probe were set
which are used in the experiment.
The transformer was set to power of 33% and the leaf blower was turned on so that the
