In contrast to the X and Y directions, the analysis of average
vibration measurements in the Z direction revealed a
different pattern. With increasing water flow rates, there was
a slight decrease in the average vibration measurements.
This suggests an inverse relationship between flow and
vibration rates in the Z direction. Possible explanations for
this phenomenon include streamlining fluid flow patterns
at higher flow rates and reducing turbulence and vibrations
in the Z direction. Additionally, the heightened stiffness
of the pipe system due to increased flow rates may have
contributed to more effectively damping vibrations.

structure interactions within pipe systems. The observed
trends across the X, Y, and Z directions indicate that the
relationship between flow and vibration rates is not uniform
across all axes. Nonetheless, analysing the vibration values in
all directions enables the identification of trends associated
with increasing water flow rates, potentially indicating the
presence of leaks.

Eco-Solution2: Reduced Water Consumption

Strategies to Reduce Water Usage

The ESI team found that using a modified water faucet
was a practical solution to reduce water consumption. The
faucet offers users the choice between mist or spray modes,
effectively reducing water usage compared to a standard
stream of water. To implement this solution, the ESI team
installed three modified faucets at the cafeteria sink. This Figure 7: Tracking and recording the
