Hi Bart,

I did a rough test tonight.  The measurements are in the ballbark.

The setup was a frequency generator and Bert Hickman's double led resonance
detector.  The lead from the resonance detector went to a brass plate, which
I stood a free standing section of metal pipe on.

I have two pieces of metal pipe, one is a 47.25" length of 1.125" diameter
copper, the other is a 48" length of 1.0" diameter aluminum.

With the pipe on a free standing stand, its ends were about 24" from the
floor and ceiling and about three feet from the nearest object in the room.


Using the equation for acoustic waves in a completely open or completely
closed resonator, the speed of the acoustic wave in the copper pipe was
about 4.452 x 10^-3c.  That is, it was about 4.452/1000 of the speed of
light; in the ballpark of what I predicted.

The equation is F = c / 2L, which worked out as:

556kHz * 2 * 47.25in = 4.452 x 10^-3c

The aluminum value was:

571kHz * 2 * 48in = 4.644 x 10^-3c

It is possible the aluminum has a higher acoustic speed than does copper.
However, the error of the double led resonance detector could be about 10%
either way as it did not tune very sharp in this setup.  I'm sure that by
encasing the copper tube in oil the reading would be much sharper and more
accurate.  Of course, this also indicates that exposed pipe is not the best
way to go due to electron and photon losses.

The pipe wall is about .035" in thickness.  If a wound coil were made to the
same dimensions of the copper pipe, and using the wall thickness as the wire
diameter, it would calculate to 1961kHz.  However, back calculating from the
pipe frequency of 556kHz, the pipe would have an effect thickness of .010".
This could be a problem for the theory I'm working on unless there is a skin
effect.

The math is close enough that it warrants further and more accurate
research.  I think I'm well on the path to quantifying longitudinal waves in
a three coil setup.  The math is far easier than I thought it would be.
