In the study, the paper shows measurement of density and specific heat capacity of different nanofluids. A temperature range of 30°C to 50 °C for a few molecule volume concentrations is displayed. The particular heat estimations of three nanofluids containing aluminum oxide, zinc oxide, and silicon dioxide nanoparticles. The work has been done at various temperature range 313K to 353K (30 to 80°C) with differing distinctive volume concentration (1%,2%3%,4%). which is the typical scope of operation of car coolants and building heating fluids. The measured qualities are contrasted and existing conditions for the particular heat of Nanofluids. In this manner, again broad connection was produced for the particular heat as elements of particle volumetric, temperature, and the particular heat of both the molecule and the base liquid from the present arrangement of estimations. The effect of nanoparticle connection was tried for both CUO also, Al2O3, ZNO in a eutectic blend of sodium and potassium nitrate. Results demonstrated an improvement in particular heat limit (CP) for both kinds of nanoparticles.
