The molecular properties like transmission of sound in nanofluids undergo changes in highly associated systems and dependent on the cohesive properties of liquids. In the present investigation an attempt is made to calculate the ultrasonic velocity and density of the prepared nanoparticles at different weight percentage with the base fluid Poly Vinyl Alcohol (PVA). Copper oxide (CuO) nanofluid was synthesized by transforming an unstable Cu(OH)2 precursor to CuO in PVA under an ultrasonication. The result shows that CuO-PVA nanofluid can be synthesized using this method. The obtained dried precursor was annealed at 300°C. The annealed sample and the dried precursor were sonicated with an aqueous solution of PVA having concentration 4wt%. For comparison, the synthesized nanoparticles are characterized by X-Ray powder Diffractometry (XRD), Fourier Transform InfraRed Spectroscopy (FTIR), Diffuse Reflectance Spectroscopy (DRS) and analyzed. After ultrasonication UV-Visible Spectroscopy (UV-Vis), Ultrasonic velocity, density and adiabatic compressibility were analyzed and the results were discussed. There is a good agreement between the data produced by ultrasonic spectroscopy and other measurements.Keywords

Ultrasonic Velocity Measurements Provide An Important Tool To Study The Liquid State. Such Studies Have Been Used To Understand Intra And Intermolecular Interactions In Pure Liquids, Aqueous Solutions And Binary Mixtures. Detailed Information About The Nature Of Molecular Interactions Can Be Obtained From Various Ultrasonic Parameter Computed. It Has Inspired Many Workers And Extensive Investigations Have Been Carried Out In Both Binary And Ternary Liquid Mixtures Using Various Methods. Acoustic Methods Have Been Applied To Estimate The Effective Debye Temperature (θd) Of Liquid Mixtures (binary). The Theoretical Approach Has Been Completely Modified And A New Approach Has Been Suggested. Binary Liquid Mixtures Have Been Undertaken For Computing The Values Of Effective Debye Temperature Using The Present Approach. There Was A Good Agreement With The Theoretical Values Compared With Standard Findings. The Necessary Experimental Data Needed Have Been Taken From Literature.Keywords
