Nanofluid is a kind of navel engineering material consisting of metal particles with a size typically of 10nm–100 nm suspended in base fluid. These fluids offer the excellent scope of enhancing the thermal conductivity of common heat transfer fluids. In the present study, Nanofluids are synthesized using two-step method. First, Ag nanoparticle is synthesized by using the wet chemical method. In this method, silver nitrate used as a precursor, sodium borohydride used as reducing agent, and then nanofluids is prepared by synthesized silver nanoparticle dispersed into DD water by using ultrasonication method without any agglomeration. Morphology of the produced nanoparticles is studied by Transmission Electron Microscopy (TEM); Ultrasonic velocity (v) has been measured for different concentrations of silver nanofluid at different temperatures using Ultrasonic Interferometer technique and then calculated other acoustical parameters like Adiabatic compressibility (β), Acoustical impedance (Z) intermolecular free path (Lf) and its thermal conductivity (k) by using modified Bridgman equation for Nanofluids. Since the addition of only a few volume percent of nanoparticles to a base fluid and significantly improves its thermal conductivity.
