Thermo-acoustic and nonlinear properties of Milk in NaHCO3 using Volume expansion coefficient

O. P. Chimankar, Ranjeeta S. Shriwas, Sangeeta Jajodia and V. A. Tabhane

Thermo-acoustical parameters of liquid mixture of milk+NaHCO3 have been evaluated with different mass concentration of NaHCO3 in milk at different temperatures 283.15K-303.15K. The Moelwyn-Hughes parameter has been utilized to establish some simple relations between the available volume, Bayer’s non-linearity parameter, internal pressure and Sharma constant. A relationship among the isobaric, isothermal and isochoric thermo-acoustical parameter have been studied and analyzed in the case of milk+NaHCO3. The Sharma’s parameter S0 remains invariant with the mass concentration over a wide range of temperature and retains its characteristics value i.e. 1.11±0.01 in case of present liquid system. The present treatment has the distinct advantage of volume expansivity, density and ultrasonic velocity measurement in a particular solution of milk to detect chemical additives. Analysis of such type is not found so far in literature.
