Have you guy's came to realize how to make the tubes actually vibrate yet?
Here's a Equation that only pertains to air flow, "Not Water."
CFM = Area * Velocity
Take for example a square duct. Say the duct is 4" x 4" and has an area of 16 square inches. 16"
To Use such a formula, Area Inches must be converted to Area Feet. Here is the Equation.
16" / 144 = 0.11111111111111111111111111111111 Cubit feet
Now that we Have the Area in feet, we can now use the equation mentioned like so.
CFM = Area * Velocity
0.11111111111111111111111111111111 * 700 = 77.7 CFM
This Equation Is based on 100 Foot of Duct, Not 8 or 14 foot.
The Point is, If the Velocity Gets to high then things tend to "Vibrate." And it can get violent and cause all sorta problems! They're Called Velocity Limits.
I have also other Equations, For Example... Say you wanted a velocity of X with an 8" tall tube. Well then what should the CFM be threw the tube to cause such velocity to happen?
Things also tend to have Velocity Limits, When constructing certain devices it has to be taken under consideration, Or else violent vibrations may go into affect.
If in your mind, you could take a moment to imagine a short tube with water being forced threw it, Would it then be possible for the tube to vibrate? Imagine a micro tube, and a micro vibration. All though The Equations aren't linked with water flowing threw a tube they can be, and they probably already have been.
The Equations that I know is Equations that I Created, I'm not saying they're not out there, They can be found if you know how to read very techniqal Equations, With symbols that will blow your mind. For me, I created my own rather than having to deal with their unknown symbols. My Equations are correct and Blunt.
My Current Equations for reverse engineering the above is digitaly stored, and at this time I cant seem to access them. I'll post if needed. What equations am I speaking of?
Example; Build me a duct that will have an output of 400 CFM with an Velocity of 700. This Duct Has to be 8 Foot in length. I have equations for that.
You could very well incorporate this into the wfc. One could take these and learn the water formulas, You could learn allot about vibrating tubes when water flows threw them.
What you Want to know, You want to know the Velocity Limit of a Particular Tube, You want to Exceed that limit to cause the tube to go into vibration.
