James Hardy Water Wheel Experiment.

Hi All,

Am getting ready to duplicate this James Hardy water wheel.

I have the Cal T10000 torpedo pump  T10000 Torpedo Pump
Max. Flow Rate - 9600 GPH
Flow Rate @ 1' - 9600 GPH
Flow Rate @ 5' - 8220 GPH
Flow Rate @ 10' - 6600 GPH
Flow Rate @ 15' - 5400 GPH
Flow Rate @ 20' - 3660 GPH
Flow Rate @ 25' - 1860 GPH
Max. Head - 30'
Watts - 1065
Outlet Size - 3"

Cal Pump Torpedo Pump -- 10,000 GPH The Torpedo pump is the first pump designed for the pond enthusiast that is lightweight, water cooled, uses no oil and can be used in or out of water. Its high volume water flow and low energy consumption makes it the most unique pond pump available, and it requires no tools for installation.    Over 10000 GPH at 1' of lift
40' power cord for convenience
Large 3" MPT Intake & Discharge for better flow
Dimensions: 15-1/2" x 7-3/4" x 6-3/4"
For XX-Large size ponds over 6000 gallons
Energy Consumption 4.8-13.6 amps
Energy Consumption 575-1600 watts
Max Flow: 9900
Max Head: 46'
1 Year warranty

Feature and Benefits: High flow for biofilters and waterfalls Cap start motor for low energy consumption Water cooled for environmental safety Non-corrosive construction for longevity Use in or out of water (below water level) Convenient handle for easy installation & service Safe for use in salt water 1 Year warranty

Pump Applications: Water displays Ponds Aeration Waterfalls To power large biofilters

I will need more information on the paddle wheel and what size of tips he was using?
I know the 1:4.5 ratio from pulley to generator was 18" and 4".
I also know at 25'/*.434 =10.85psi will create a thrust of (1.57*psi *d*d) or if it was 1" tip the total thrust will be (1.57*10.85psi *1"*1")=17.03 lb of thrust. Basis on water rocket thrust formula, it's the right formula!

(18"/12)/2=.75' constant pulley load or 17.03*.75=12.78ft/lb

The total FPS of thrust is SQR(32+32*(10.85psi/0.434))=40fps
My question is how big was the paddle wheel?
If it was 18" then pi*18=56.55 or 4.71ft
This means total rpm without any load would be (40*60)/4.7=510.64rpm's and with the 1:4.5 ratio the generator speed is 510.64*4.5=2297.87 rpm's.
But the torque is now down to 12.85/4.5=2.85lb generator pulley load.
Even with max output at 100% you get (2297.87*2.85ft/lb)/5252=1.24hp or 930.2 watts of power.


Input is needed ASP.

That pulse water wheel is a legitimate device.

If you make it right you will succeed.

Hi Armcortex,

I do question this build, but it should be fun also.

I will try to keep it simple, I must first try to get the max flow and pressure from the pump verse watts needed.

And then it's plain and simple with a basic water wheel design I can calculate rpm's torque and output on generator head...

I think that the key to this "water wheel invention" is the battery denoted with the number 6 in the drawing of the patent depicted here http://www.overunity.com/5176/selfrunning-waterpump-generator-device-runs-60-watts-lamp/msg113275/#msg113275 . (The patent is also attached.)

The battery (if charged) will drive the contraption for some time. A 30 second run would not be a surprise.

Even if the switch (5) is off, the transformer (2) and the battery charger (4) might connect the battery to the pump. It is not clearly specified in the patent how the transformer (2) and the battery charger (4) are wired internally. In the patent it says that the transformer puts out DC current, which suggests that it is more than a simple "transformer" and the "battery charger (4)" could be anything (e.g. a simple full bridge rectifier).

In any replication this "battery problem" has to be clearly resolved. I am sure you are aware of this important detail.

The water wheel in the video looks like being very inefficient in relation to the amount of water being pumped. And please be careful with water near a 110V or 220V genarator, it can kill.

Greetings, Conrad

Hi Conradelektro,

I that you for your input.

I also understand being shock by 120v ac, but really depends on the eletrolite in the water that increase watts.

I was thinking in those terms also using a alternator first and a inverter to drive the pump. But before any output, I must find the max load of the thrust and fps to get a better idea of what it can power.

Thanks.

Tom
