DISCHARGE OF WATER DUE TO THE PRESSURE
The gray part on the drawing represents the partition.
The rounded design on the back side limits the swelling
of the rear portion of the Water Force and forms a single
unbroken line with the upper part of the canvas. Thus
preventing any weakening which could create a tear
from the wall. (The rounded part “Arc” is small enough
not to create tension on the point “from the seam of
the partition”).
The pressure exerted on the upper canvas raises the partitions leaving a discharge space so that the
incoming water is not trapped below the surface of the Water Force.
CALCULATION OF THE PRESSURE
Since we know the highest points of tension exerted on
each partition, we can calculate the force exerted
in order to ensure that the partitions resist
more than 3 times the pressure
of the water (a norm estab-
lished for Water Force
products) to insure a very
safe and reliable product.
The partitions of the Water Force are made of non-expandable
polyethylene, a rigid material recognized for its strength. These
partitions prevent the upper canvas from tipping backwards via
the components principle of equilibrium of forces.

BEHAVIORS AND STRETCHING OF THE PARTITIONS
PRESSURE EXERCISED ON ANY PART OF THE PARTITIONS
In this illustration, we can observe the pressure exerted on each part
of the partition. The red indicated the robustness to tension
applied on each partition.
We can observe an area which has a point of force
superior to any other. It is here on the partitions that
receive the most tension. It is also at a point which
our calculations of strength and sturdiness have been made.
The tensions inscribed on the canvas are gures based on our expertise and our observations.
