RESEARCH APPROACH -1- Assess if the volume of a Bourdon tube changes on pressurization. -2- Investigated current engineering and scientific knowledge on the subject. -3- Investigated other attempts of identifying Bourdon tube characteristics. -4- Formulated experiments to determine Bourdon tube characteristics. THE BOURDON TUBE EXPERIMENT -1-The need was to provide an alternate and simple demonstration, supporting the diamond-shaped actuator patent, suggesting that the Laws of Thermodynamics have over-looked important fluid relationships, regarding energy/mechanical work. Successful experiments would also confirm Pascal’s Principle. The intent was to determine if a Bourdon tube with a lesser pressure range than a second bourdon tube will produce enough work at its tip to pressurize the second Bourdon tube, producing work at the tip of the second bourdon tube greater than the work of the first Bourdon tube. -2 We contacted many gauge manufacturers to determine if the volume of a Bourdon tube changed when being pressurized and depressurized. A few thought the volume did not change: most had no data on the matter. -3- Cynthia Conway in her 1995 Engineering Masters thesis investigated the question regarding Bourdon tube characteristics. She was required to assume the volume changed as she found no conclusive data on the matter after extensive investigation. The concluding result is that it appears unknown if the volume changes in a Bourdon tube when pressurizing and de-pressurizing.

The adaptation compensating for small volume changes is addressed in the patent, "PATENT USING BOURDON TUBE CHARACTERISTICS". 12.213 BOURDON TUBE WORK IN < WORK OUT ASSESSMENT
