1.0 ABSTRACT

This experiment is aimed at investigating the validity of Bernoulli’s equation when applied to

a steady flow of water in tapered duct and to measure the flow rate of steady flow rates. Based on

(Bernoulli’s theorem, 2011) relates the pressure, velocity, and elevation in a moving fluid the

compressibility and viscosity (internal friction) of which are negligible and the flow of which is

For this experiment, by using the FM 24 Bernoulli’s Apparatus Test Equipment is to

demonstrate the Bernoulli’s theorem. The experiment was conducted in order to find the time

taken to collect 3L of water, the volumetric flow rates of the water, the pressure difference at all

manometer tube at different cross section. The time to collect 0.003 m

water is recorded based

on the different flow rate for each experiment.

The combination of venture meter complete with manometer tube and hydraulic bench

were used. During the experiment, water is fed through a hose connector and the flow rate can be

adjusted at the flow regulator valve at the outlet of the test section. The venture can be

demonstrated as a means of flow measurement and the discharge coefficient can be determined

the results show the reading of each manometer tubes increase when the pressure difference

increases. From the reading of height can be calculated the data by applied the Bernoulli equation

to fin the velocity of the fluid moving.

The pressure level and velocity reading for part A to E of the tube is recorded. From

Bernoulli theory, the relation between the increase and decrease in the pressure value is inversely

proportional to its velocity. Bernoulli's Principle tells that as the fluid flows more quickly through

the narrow sections, the pressure actually decreases rather than increases. Thus, it proves the

validity of Bernoulli’s theorem
