Theoretical computation of sound velocity and their bulk modulus for many lubricating oils having various applications in machinery and daily lives at different ranges of temperature over the entire concentration range has been done from the measured data of Mia and Ohno. An attempt has also been envisaged to predict the molecular interactions and molecular structure involved therein and also to establish relationship among sound velocity, surface tension, adiabatic compressibility and their bulk modulus. It is found that theoretical results for sound velocity agreed well within the experimental precision when compared with experimental data. These properties are helpful in predicting the group of the lubricating oil of which they belong.

Abstract


Theoretical computation of sound velocity and their bulk modulus for many lubricating oils having various applications in machinery and daily lives at different ranges of temperature over the entire concentration range has been done from the measured data of Mia and Ohno. An attempt has also been envisaged to predict the molecular interactions and molecular structure involved therein and also to establish relationship among sound velocity, surface tension, adiabatic compressibility and their bulk modulus. It is found that theoretical results for sound velocity agreed well within the experimental precision when compared with experimental data. These properties are helpful in predicting the group of the lubricating oil of which they belong.
