The measurements of Ultrasonic velocity, Compressibility, Density, Acoustic impedance, Inter molecular free path length, Bulk modulus, Rao’s constant and Surface tension have been determined using nanofluid interferometer model NF-12X operated at 9 MHz frequency. Specific gravity bottle was utilized to measure the density of the nanofluids. The synthesized nanofluid is characterized by X-Ray diffraction (XRD), Scanning Electron microscopy (SEM) and optical studies. The Electrical conductivity was measured for different concentration using Digital conductivity meter model-RI 503.
base fluid like water, oil, acetone, heat transfer fluids, polymer solutions, bio-fluids and etc. These dispersing nanoparticles have dimension of 1-100 nm [1].The term nanofluid was coined by Choi [2]. Nano fluids have very diverse application in various technical fields which includes nano electronics, transportation, nuclear physics, nano solar collectors and biomedical science [3]. Fluids are categorized as metallic or nonmetallic. Nanofluid is also not an exception for this. But nanofluids are classified on the basis of behavior of colloidal particle in the base fluid [4]. There are two phases of nanofluid system one is liquid and another is solid. The stability of the fluid determines the life time of nanofluid. The method of preparation of these nanofluids generally follows in two methods: a) one-step method, b) two-step method. The dry nano sized powders is produced first either physical or chemical process at the second step of two step method the produced nano sized powders is made to dispersed into the base fluid with help of intensive magnetic force agitation, ultrasonic agitation, high-shear mixing and ball milling. In contrast to this in one-step method simultaneous making and dispersion in base fluid occurs at the same time [5].

INTRODUCTION The colloidal suspension of nanoparticles in the base fluid has turned now into the most advanced and dragging field in science due to the enhanced thermal conductivity than the traditional base fluids. Nanofluids can exhibit better heat transfer characters in the heat exchange systems and electronic cooling systems which is one of the natural advantages of nanofluids which the field of industry is starved for more than three centuries. nanofluids
Ultrasonic pulse velocity test in which the longitudinal ultrasonic waves has been used and it has become the most valuable tool for the study of various chemical and physical properties of the matter [6]. It is an important fact finding technique in the fields of fiber optics, optical metrology, astronomy, remote sensing and plasma physics. An ultrasonic interferometric sensor has used to measure suitable changes in the physical properties of fluids such as density, viscosity, surface
