ESTIMATION OF SHARMA CONSTANT AND THERMOACOUSTIC PROPERTIES OF FATTY-ACIDS

From the volume expansivity a, a number of thermoacoustic parameters, including the Sharma constant, So, are estimated for four fatty acids as a function of temperature. The Sharma constant, which was establish ed to be a constant with the characteristic value 1.11 +/- 0.01 over a number of systems investigated by earlier investigators, is also foun d to be a constant with the same value for all fatty acids under inves tigation. Further, the Sharma constant, So, is independent of temperat ure and dependent only on a. All other parameters estimated are discus sed and compared with the values reported in the literature by earlier workers for different systems.
