The device is now rotated through a north-south plane perpendicular to the earth's surface.
To begin the test it was necessary to set the water flow rate at the minimum required to keep the system functioning properly. Rotating the device between the up and down positive stop points resulted in a shift of only three wavelengths and this of course occurred when the pointing direction was parallel with the earth's surface. The interference pattern returned to where it started from when it reached the down stop.
As previously, the interference pattern shifts according to Freznel's prediction as the water velocity is increased. The pattern now shifts in that same direction when the device is turned from pointing downward to point upward. And that shift is directly proportional to the water velocity.
Example: According to the zero origin concept, the base on which light propagates is shifting inward through the earth's surface at the rate of 19.6 m/sec. v = 19.6 Predicted inflow of dimension (m/sec). wv = 6.1 Water velocity per second (as previous example). n = 1.332 Water/air refractive index. l = 3.6 Water path length (times two). c = 3E+08 (for a water velocity of 6.1 m/sec) The orientation of the device is set so that the water flow is pointing downward. Relative to the base of dimension on which light propagates, the water is traveling at (v-wv) = 13.5 m/sec. Light is dragged by (v-wv)*(1-(1/n^2)) = 5.89104 m/sec. The orientation of the device is set so that the water flow is pointing upward. Relative to the base of dimension on which light propagates, the water is traveling at (v+wv) = 25.7 m/sec. Light is dragged by (v+wv)*(1-(1/n^2)) = 11.21479 m/sec. The difference is 5.323754 m/sec of water path length, which is 5.323754 / 3E+8 * 3.6 = 6.388505E-08 meter shift. = 63.88505nm / 634nm laser wavelength = .1007651 fringe shift.
The result is always exactly the same for any specific water velocity regardless of how fast the propagation base for light is shifting past the device, so long as the velocity of light's propagation base isn't exceeded by the water flow rate.
As in the previous test, when the pump is running at 5000 rpm, close to 1/3 of a fringe shift is noted.
My apparatus isn't capable of pumping enough water velocity through the water path to prove that light propagates on a base that's moving into the earth's surface at the rate of 19.6 m/sec, but it can be done.
