For the vertical position, it consists of three positions which is at the center of the
propeller, port 100 mm, and starboard 100 mm and this is the fourth variable in this
study.
The fifth parameter is the depth of the measuring device where there are four
different depths of the measuring device, i.e., 30 mm, 60 mm, 90 mm, and 120 mm
in depth.
The last variable is the speed of the motor. There are four different revolutions
per minute in this experiment, i.e., 300 rpm, 600 rpm, 900 rpm, and 1200 rpm.
Next is the equipment and device used in this experiment. For the hardware
component, this experiment consists of a tank to store the water and mounting for
the propeller and motor. For the electronic component, an Arduino board is used
as micro-controller and other components such as a diode, transistor, resistor, and
connecting wire where it is connected to the bread board. A 12 V DC motor is used
and this experiment is using a 9 V rechargeable battery to support the electronic
component. A LCD panel is used to display the value of the rpm set in the Arduino
board.
17.2.2 Implementation of the Experiment
This section covers the hardware component assembling and electronic component
assembling. The assembling component flowchart shown in Fig. 17.2.
For the hardware component the mounting for the motor and propeller is made
from wood that has been cut in suitable length to be able for the motor and propeller
to sit in a place as shown in Figs. 17.3 and 17.4.
Later the mounting is installed in the tank and ready to connect with the electronic
component thus to begin the experiment as shown in Fig. 17.5.
For the electronic component, all the components are connected together through
the breadboard. It is tested first before connecting it with the motor and propeller as
shown in Figs. 17.6 and 17.7.
After the circuit is tested without fault, it is ready to be assembled together in the
tank as shown in Fig. 17.8.
17.2.3 Method to Collect Data
Table 17.1 is used to show the collected data. The information of the independent
variables is shown in Table 17.2 and the details of the propeller size and numbers of
the blades is shown in Table 17.3.
The experiment has been conducted using the method shown in Sect. 17.2. The
graph is plotted based on the result in Table 17.4 to show the comparison for each of
the parameters.
