James Hardy Water Wheel Experiment.

[Tommey Reed]

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.

Ok, got a simple water wheel going, now I need to improve on output of mechanical work...

Enjoy the show.

Summer time fun for the kids!   

Curious to see what kind of torque you can get with more and larger cups on that wheel.  May also want to consider a larger wheel--balance between speed and torque.

Hello All,

The problem with the James Hardy water wheel is power to the water wheel and flow.

I will have to get a bigger flywheel with paddles and see if I can get enough torque to do work.

I like to add my water project to this experiment also.

This is a water design I call the Submersible Displacement Engine using waves to generate compress air that gets feed down to the displacement tubes.

As air is trap, it cause the displacement to rise to the surface.

This is a simple test using this design as a efficient water wheel.
