Hydro Differential pressure exchange over unity system.

Mond's data looks a lot better if the first two trials are discarded as outliers. There is still something happening during the first seven or eight trials, then a period of constant performance, then another upwards trend. But leaving out the first two from the means and stddevs makes the set a lot less noisy and more consistent overall.

One thing I noticed yesterday is that the Outer Riser tends to want to rotate, probably due to the vibrations from the shaker motor.  As it rotates the piece where the height indicator is touching will move.  So this may slightly change the readings on that indicator.

Another thought:  Since the Pod and Risers are NOT locked together, the Inner Riser and Pod may be rotating separately of the Outer Riser.  And since nothing is truly square in this build any rotation of either inner member may cause a change in the tilt of the Outer Riser end cap.  Any minor tilt changes can affect the indicator readings quite a bit.

Back to the topic of how to properly measure this single three layer (1 Pod, 2 Risers) ZED set up.  What is the opinion of the method that Wayne outlined in #2505?  I'll post the relevant section below in bold, not for emphasis, but just to delineate where his content starts and ends.

Lets say your load was 10 lbs (corrected by M), if your pressure increase is .215 and your stroke is .75 inches, and your volume was 27 cubic inches.

Here is the method - 27/.75 = 36 this give you a comparative piston value - 27 cubic inches could lift (in a frictionless position with a surface area of 36 inches a stroke of .75 inches.

Now multiply the pressure difference of .215 x 36 = you could lift 7.75 pounds (roughly)
Now compare your 7.75 to your actual lift of 10 pounds the same difference.

10/7.75 = 129%

Is this a valid method for evaluating input vs. output?

I see that mrwayne has updated his website today. He states that the time for handing over to the team for validation is likely to be this coming Friday. He also speaks of the next phase which heis calling the "Rotary Zed." Have a look for yourselves.
