Understanding Water in Motion
Consider the glass of water to the left. This illustrates water in its fully compressed, liquid form. This is the same as Laminar Flow.
As soon as you begin to move water, its natural tendency is to expand from its fully compressed liquid form to its expanded fluid form, which is comprised of water as a liquid, vapor and gas form, illustrated on the right.
Note: Vapor bubbles are what is responsible for Cavitation.
Application of Boyle's Law.
Boyle's Law states that pressure and volume have an inverse relationship, as pressure increases, volume decreases.
This tells us that if we can create a point of compression that returns water to its compressed laminar flow form, then water in its uncompressed (turbulent and expanded) form can't pass through this compression zone.
The WATERGATER Flow Management Valve does exactly this. By installing the valve on the PROPERTY side of the water meter, the WATERGATER creates a compression zone against the incoming water flow. Without restricting your water flow or reducing the incoming PSI, the WATERGATER squeezes the turbulence out of your incoming water line, preventing air and water vapor bubbles from passing through your water meter, achieving Laminar Flow.
Bringing it all Together
The image above reflects the shape of most commercial property water meter setups. The incoming water line will be reduced down to the water meter size and then expanded back to the original size.
This creates a Venturi Tube.
The incoming turbulent water flow must match the outgoing water flow. This means water flowing through the smaller, middle pipe (the water meter), will travel at a much higher velocity, creating a low pressure zone.
As Boyle's Law told us, this low pressure zone will cause the water to expand even more, creating an abudance of vapor bubbles.
The Result: Hydrodynamic Cavitation
Hydrodynamic cavitation describes the process of vaporisation, bubble generation and bubble implosion which occurs in a flowing liquid as a result of a decrease and subsequent increase in local pressure.
In pipe systems, cavitation typically occurs either as the result of an increase in the kinetic energy (through an area constriction) or an increase in the pipe elevation.
Cavitation is a significant cause of wear in some engineering contexts. Collapsing voids that implode near to a metal surface cause cyclic stress through repeated implosion. This results in surface fatigue of the metal causing a type of wear also called "cavitation".
Over time, this cavitation leads to pin-hole leaks and erosion of joints and pump impellers.
The Solution - WATERGATER
The WATERGATER creates a compression zone that leverages Boyle's Law, by increasing the amount of pressure the incoming turbulent water is subjected to.
By installing the WATERGATER just after the water meter, on the property side, the compression zone extends backwards through the water meter and onto the utility side. This ensures that the water coming into your property is compressed and not given a chance to create vapor bubbles, restricting its ability to expand.
By accomplishing this we achieve Laminar Flow.
