Abstract: This article outlines the effect of adding Al2O3 and Cu nanoparticles to water and measuring the thermal conductivities and viscosities of the mixtures. The effect of pH was taken into account and it was found that there are optimal pH values for each of the nanoparticle mixtures that give the highest thermal conductivities and lowest viscosities. Research shows that thermal conductivity and viscosity are closely related to each other. The optimal concentration of nanoparticle was found to be 0.4 weight %. The increase in thermal conductivity of the water was significant upon addition of nanoparticle.
