Building a Clem's engine

[TommeyLReed]

My new youtube channel.
This is the first high speed test using 250-300psi to reach speeds above 3,000 rpm's.
This is a simple pipe setup to prove that cooking oil could run a Richard Clem engine.

I also calculated the thrust at 250 psi with two 3/64 jets:
(pi/2 * 250psi * 3/64 *3/64)=.86lb thrust for each jet, a total of 1.72lb thrust.
The velocity is :
250psi/.433 =577.4
V=sq/root (2 *32 * 577.4)
Velocity=192.2fps.
 
The diameter of the rotation was about 12"
Circumference (12*pi)/12=3.14ft
Peek RPM's (192.2fps*60sec)/3.14ft=3672.6 rpm's.

Lets start with the Clem's engine output.

Richard Clem Said the the motor produce 350hp at 2300 rpm's as he claimed:
hp=torque ft/lb * rpm/5252
That would mean that 350hp * 5252/2300rpm=799ft/lb of constant torque.

That is alot of torque, but if you break it down it looks like this:

I believe a 3ft diameter drum would work.
3ft diameter drum you would need (799/1.5)=532lb of thrust.

using 32 jets will mean that each jet will need only (533/32)=16.7lb of
thrust
using 16 jets will mean that each jet will need only (533/16)=33lb of
thrust
using   8 jets will mean that each jet will need only (533/ = 66lb of
thrust

The torque need at 350 hp, I would use more jets at lower thrust then
less one that will need greater volume and pressure.


Each jet will need for THRUST = 1.57 * 900psi * 0.125( jet)od *
0.125(jet)od=22lb of thrust and reach rpm's greater then 2300.

This does not include the rotational inertia effects on the jets, that
will create it's own head pressure..

Just some basic data, tells me alot.

I would go with a low power system, but at high rpm's to run a
generator.

This would prove if OverUnity takes place.

Glad your still around!  Thanks for the update.

Why not do a definitive test of your nozzle force.  You could put a scale on the end of a 1 foot  pipe rotor and test different nozzles to see what actual force is being generated at that distance. With that torque knowledge you could easily calculate number of nozzles needed and capacity of the pump to supply them.

I agree, but right now  have to finish this other prototype.
I need to test the rpm's and input load. The rotational inertia should decrease in motor load, due to creating it's own head pressure from the inertia.

tom, i miss your you-tube videos, you need to make more.
