ABSTRACT
The purpose of this experiment is to investigate the flow rate/discharge and the head loss of 3 particular flow measuring apparatus which are the Venturi Meter, Orifice Meter and Rota Meter in accordance to Bernoulli’s Equation. The time taken for the water to discharge as the diameter of Rota Meter increased was determined and tabulated. Then, the discharge & head loss for each apparatus is calculated using the data obtained through the experiment and the calculations were tabulated. The results were analyzed and its accordance to Bernoulli’s Equation was discussed. The experiment was completed and carried out successfully.
Introduction
The flow measuring apparatus is used to familiarize the student with typical methods of flow measurement of an incompressible fluid and, at the same time demonstrate applications of the Bernoulli’s equation.
The flow is determined using a Venturi Meter, Orifice Meter and a Rota Meter. Head losses associated with each meter are measured directly from the manometers. The head losses arising in a rapid enlargement and a 90o elbow can also be measured.
Firstly, water enters the apparatus through the lower left-hand end and flows through the Venturi Meter, followed by the Orifice meter then through 90o elbow and finally through the Rota Meter. All connections to the manometers panel are made from clear plastic tubes. Upon leaving the Rota Meter, the water flows via a control valve into the flow measuring hydraulic bench.
The Venturi Meter consists of a short converging conical tube leading to a cylindrical portion, called the throat, of smaller diameter of that of the pipeline, which is
