Abstract: The main objectives of the present work embrace the preparation of cobalt nanofluids, amalgamation of silica nanofluid with optimum glycerol-water (G-W) mixture ratio and estimation of its thermal properties like thermal conductivity and viscosity experimentally. Optimum ratio of base liquid (G-W mixture) was selected for the preparation of nanofluids. Subsequently, thermophysical properties of the hybrid nano mixture have been determined experimentally using KD2Pro thermal properties analyzer and Brookfield viscometer at different volume concentrations of silica nanofluids. Attained results reveal that, the dynamic viscosity and thermal conductivity are found to be growing remarkably with the increase in nanoparticle weight concentration in base liquid mixture. The results are found to be in good agreement with the available data from the literature.
