WATER-POWERED DC HUB
CHARGING SYSTEM
Balbin, Burdeos, Cajuday, Malazo
• Improvement of the green technology by using renewable
energy involving water resource.
• Guide to create a microscale renewable energy source for
charging of low power DC loads intended for off-grid areas.
• This research project covers fluid dynamics involving Heron’s
principle, calculation of voltage output relative to amount of
water in the containing vessel and validation of data and
results using Pearson’s correlation technique.
Fig. 1– Enabled Heron’s Fountain.
Provided that the air tank has air,
the water will resume to rise.
Fig .2 – Disabled Heron’s Fountain.
The execution of the system
will increase by the volume
of the tanks.
Fig.3 – The Projected System.
The concept is a closed system where the air
will be enclosed in the system which will be
achieved by closing the cap of the tanks.
Fig.4 – 180 degrees rotating to reset.
It is shown that the water and air circulating
in the system will be back to their respective
tanks.
Fig.5 – Generating Power and Regulating Voltage.
This picture represents the hydro-electric power
generation with a voltage regulator that would
efficiently give the estimated output of 5 volts.
Bernoulli's Equation
 Decision Criteria
There is a directly proportional relationship between
two factors if the Pearson’s correlation value, r, is
within 0.5 and 1, there is inversely proportional
relationship when Pearson’s r is within -0.5 to -1, while
there is little relationship when Pearson’s r is -0.5 to 0.5.

 Interpretation of Data and Results
There is a direct relationship
between the volume and the
output voltage using the
Enhanced Heron’s Flow.
 Multisim Simulation
• The volume filled of the upper tank is directly proportional to the
output voltage of the regulator side.
• The voltage that can be generated using the micro-scale hydro
turbine generator ranging between 4.622 volts to 5.038 volts.
• The volume filled and the output voltage have a direct
relationship, based on the Pearson’s correlation.
• The Watered-Powered DC hub charger prototype is not a
perpetual source of renewable energy.
• In this study, the researchers proposed a design that
utilizes hydroelectric energy at a micro-scale level
intended for off-grid areas.
• This research project can serve as a basis in the
development
of
water-powered
electric
generators
adapting the Heron’s principle with modified system.
•
Replace the turbine generator from 5 volts to 12 volts with higher power rating for
some DC load applications.
 The level of the water on tank is hard to know, the researchers recommend to
have a sensor or sight glass in every tank to verify the water level.
