Relationship between the inertia and sensitivity in pressure-measuring systems

Conclusions

• 1. The authors determined the relationship between the inertia and sensitivity of the flow chamber and showed provided that the other wavelength, i.e., λ₁ is exactly known. The ratio of the frequencies with which the interference patterns are shifted is denoted by n=f ₁/f ₂.

• 2. An empirical equation is recommended for determining the discharge coefficients of open and ball-type nozzles which agrees with the experimental results with an error of less than 5%.
