Bernoulli s Theorem Demonstrator.
Bernoulli's Theorem Demonstrator facilitates
the students and the industrial professionals to explore the
fundamentals of “Bernoulli's Theorem” in Fluid Mechanics. It states
that, in a steady flow the sum of all forms of mechanical energy
(kinetic, potential and pressure energy) in a fluid along a streamline
is the same at all points on that streamline. It consists of classical
venture of clear acrylic. A series of wall tapping allows measurement of
static pressure distribution of convergent duct, while a total head
tube is provide at the centre of throat. These tapping are connected to
a bank of manometer tube. This unit has been designed with Hydraulic
Bench to study the characteristic flow through convergent and divergent
section. During the experiment, the water fed to the venture and the
flow rate can be control by the gate valve at the outlet of venture. The
venture is used to demonstrate the flow rate measurement and to
determine the co-efficient of discharge.
