Has An Important Property Of Fluids Been Overlooked ?

Ralph, I see your problem. You are omitting the third dimension required for calculating volume. You are using the average circumference times the 3 inch width. This give area rather than volume.
Before I do the calculations, let me get something straight. If you slice thru the "doughnut", what is its cross-section shape. The reason that I ask is that you state 24.75 inch inner radius and 36 inch outer radius. This difference is 11.25 inches. Thus your description is NOT a torus. And thus I assume the cross-section is rectangular?

I'm assuming you are describing a hollow cylinder?
The formula volume of a hollow cylinder is Pi × h × (R^2 - r^2)
If outer radius of cylinder is r = 36 and inner radius r = 24.75 and cylinder width is h = 3 then...
V = Pi × 3 × (36^2 - 24.75^2)
V = 6441.25 cu/inch = 27.88 gallons = 105.55 liter.

Jim,
Thank you for the response and your assistance: The cross-section shape is rectangular. It is as you state 13.5 inches from inner to outer ring, 3" wide . This gives me an area of 13.5 X 3= 40.5 square inches.
This means I also flubbed the dub on the inner radius, if I subtract 13.5" from 36, my inner radius is 22.5"... This changes the diameter to 45" for a circumference of 141.37". Outer diameter is 72" and I believe my circumference of 226.11� is correct, but right now I am to confused to assure anything.

Thanks again Jim,
Your latter post and mine with updated figures crossed paths in the mail.
Your calculations are within the ballpark giving me of how much liquid it will hold and from that I can calculate weight.
The actual volume will decrease when I take into consideration the volume utilized for the 105 turbine blades!

Jim,
Once again; I thank you!
Your calculation of 27.88 gallons gets me in the ball park and close enough to continue. I now know that I am looking at 232.66 pounds (105.5kg) of water.
Should be sufficient to make a very efficient flywheel with a free open vortex.
Quote from Wiki: (last sentence)
In fluid dynamics, a vortex is a region in a fluid in which the flow is rotating around an axis line, which may be straight or curved.[1][2] The plural of vortex is either vortices or vortexes.[3][4] Vortices form in stirred fluids, and may be observed in phenomena such as smoke rings, whirlpools in the wake of boat, or the winds surrounding a tornado or dust devil.
Vortices are a major component of turbulent flow. The distribution of velocity, vorticity (the curl of the flow velocity), as well as the concept of circulation are used to characterize vortices. In most vortices, the fluid flow velocity is greatest next to its axis and decreases in inverse proportion to the distance form the axis.
In the absence of external forces, viscous friction within the fluid tends to organize the flow into a collection of irrotational vortices, possibly superimposed to larger-scale flows, including larger-scale vortices. Once formed, vortices can move, stretch, twist, and interact in complex ways. A moving vortex carries with it some angular and linear momentum, energy, and mass.

Me,
Not quite! the area diameter inside the inner rim of the accumulator is vortex/fluid free. The idea is to keep the majority of the liquid velocity turning with the machine vortex free keeping it centrifugally symmetrical to the outer rim.
The machine can either turn clockwise or counter clockwise at the operators discretion, simply by moving a fixed lever 180 degrees.
Please be patient and allow me more research time before responding to your link:

This is a good one and needs to be handled with clean gloves!

Your above depiction of an automotive torque converter is a good example for explanatory purposes. but needs a few modifications.
My built 72" (182.88 cm) diameter design is rectangular when viewed in a cut-away drawing, There is a total of 105 fixed blades making up the rotor and stator. All blades measure 2 X 3 x .75" thick for a total volume of 472.5 cubic inches (7.74 cc or liter). This volume must be subtracted from turbine volume when calculating liquid capacity.
Blades make up Three rows radial to the axis located in 10.28 degree intervals. the inner and outer are on matching radial planes, the middle row (aka stationary stator) is 5.14 degrees offset.
The complete accumulator/turbine is water proof encased within two laminated layers of .125" (0.3175 cm) tempered hardboard and the blades are utilized as the structural frame. A plastic barrel bung is installed in the outer rim for filling the unit.

How are you pumping at a higher rpm to cover the volume difference? The inner area is 3 times smaller than the outer area.

re: Has An Important Property Of Fluids Been Overlooked ?
Fcdriver,
I am sorry but I do not understand your question. I am not attempting to pump the liquid any faster than the turbine blades in the accumulator turns. If as noted; centrifugal force becomes exponential with velocity and angular momentum the machine will do its own pumping.
There is as this topic states a lot about fluid dynamics and mechanics that are being overlooked. One source that is worthy of gaining knowledge deals with "Specific Gravity Classification" as used in separating heavier mass in alluvial deposits (aka placer mining). Using cavitation created by Hungarian riffles to separate/isolate heavier gemstone and metals from country rock.
It is this cavitation process set up by the orientation of the turbine blades that make my design always maintain a OB displacement. The term "Buoyancy" does not apply to my design.
In my attempt to keep friction to a minimum, moving parts have been machined for a loose fit. It is deliberately designed to be self lubricating by the small passage of liquid used as the driving force.
The only pumping required is to gather this bi-passed liquid into a sump pan placed under the machine and pump it back into the accumulator. A small 12 volt marine bilge pump will more than accommodate this function.

The torque converter image reminded me of two events in my past.
In one, while I worked at my fathers service station, he told me of an electrician who lived nearby in town. He designed a free energy system based on a torque converter modification. As my father put it, he was approached by big oil and the device never saw the light of day. He retired a wealthy man.
In another event, I communicated with a fellow who lived in southwest Florida that developed a working torque converter free energy device. He said he had a video but I never saw it. He said it looked like two torque converters welded face to face.
Maybe there is something hidden in the torque converter design that could generate free energy?

To find out how much available force it takes to move a Newtonian fluid (water) I suggest one starts by building a simple Prony brake as described by jim_mich here:
http://www.besslerwheel.com/forum/downl ... er=user_id
and here: https://en.wikipedia.org/wiki/Prony_brake
Attach two like open top containers with a hose and valve connecting the two. It is crucial that they be the same distance from the axis and that they weigh the same keeping the device level and balanced.
Set Your bathroom scale under the right side and shim so that it is just touching the brake. Fill the left container with water, this side will obviously fall if not supported.
Now, as abruptly as possible open the valve allowing the water to seek its own level left to right. Keep your attention glued to the scales! Once the water is in motion you will note that it flows past the level mark and increases the scale reading momentarily before balancing out, and the now oscillating flow ceases.
