Bernoulli's Principle

OBJECTIVE
experiment is done to investigate the validation of the Bernoulli’s equation and also to measure pressure distribution along venture tube.

INTRODUCTION
This experiment is carried out to investigate the validity of Bernoulli’s theorem when applied to the steady flow of water in tapered duct and to measure the flow rates and both static and total pressure heads in a rigid convergent/divergent tube of known geometry for a range of steady flow rates. The Bernoulli’s theorem (Bernoulli’s theorem, 2011) relates the pressure, velocity, and elevation in a moving fluid (liquid or gas), the compressibility and viscosity of which are negligible and the flow of which is steady, or laminar. In order to demonstrate the Bernoulli’s theorem Bernoulli’s Apparatus Test Equipment issued in this experiment.

THEORY
• Velocity of fluid is less fluid
• The fluid is incompressible and non- viscous
• There is no heat energy transferred across the boundaries of the pipe to the fluid as either a heat gain or loss.
• There are no pumps in the section of pipe

For an ideal fluid flow the energy density is the same at all locations along the pipe. This is the same as saying that the energy of a unit mass of the fluid does not change as it flow through the pipe system.

APPARATUS

EXPERIMENTAL PROCEDURE
1, A inspection was done to ensure that the unit was in proper operating condition, so that the experiment will not consist of errors.
2, A hose had to be connected to the nearest power supply.
3, The discharged pipe was then opened.
4, The cap nut of the probe compression gland was set to such condition, that the slight resistance could be felt on moving the probe, and the water flow created a sound which also helps to determine the flow pressure (by hearing it ).

5, The inlet and outlet valve was then opened.
6, Then the pump was switched on and the main cock was released slowly opened. 7, The vent...
