19.4 Data Analysis
This chapter contains the result and the corresponding discussion for the project
experiment that has been conducted and completed successfully. This chapter is
divided into several sections according to the variables to explain the data of the
result. Each data set is recorded into tables and plotted into graphs for better analysis
and comparison throughout the experiment.
19.4.1 Sources of Data
The experiment was conducted using the method shown in Sect. 19.3 that used
Table 19.1 to collect data and the result gathered to form a graph to show the result.
The graph is plotted based on the parameters to show the comparison for each of the
parameters.
As from the results, power output is created when water flows into the hydropower
unit and makes the turbine turn. This action makes the stator and rotor of the electrical
generator spin where it creates the current. From there the current is distributed
by wire. Various parameters were used to identify the best situation to generate
electricity.
This experiment tells that each parameter shows a different power output. In
theory, the greater the water flow, the greater the electrical current produced.
19.4.2 Free Fall Power Output Data
From the graph in Fig. 19.4, it shows that the power output of the hydropower unit
for free fall is greater when the distance between two tanks were higher. As shown,
all three numbers of blades produce more electrical output at 1.5 m compared to
other height recorded and plotted.
Meanwhile, in the experiment of the 3/4
diameter pipe for free fall experiment
shows same trend with 1/4
diameter but lower in electrical power output as shown in
Fig. 19.5. This happens because the surface area of the 1/4
diameter is smaller and
this creates more pressure than 3/4
diameter. Moreover, the pressure also comes
from gravity forces where the formula of ρ x g x h, applies. Thus, the higher the
distance between two tanks will create more pressure, thus increasing the water flow
to the hydropower unit.
