Technical Examples

A technique for determining particulate density in a fluid monitors the changes in the speed of sound. Since the speed of sound is intimately related to the composites of the air mixture and since the speed of sound of clean air at any temperature and humidity can be calculated exactly, it is possible to estimate the density of any foreign particulates in the air by observing changes in the speed of sound. Formulations are derived that correlate the change in the speed of sound of the air mixture to their density fluctuations, thus allowing people to estimate the mass density of foreign particulates under any temperature and humidity. Alternatively, the change in density of the air mixture can be detected, thereby indicating the presence of contaminants and a possible alarm, even if the contaminants are not yet identified.
