In this article, a new simple empirical model is proposed for the prediction of the viscosity of nanofluids which is only a function of volume fraction of nanoparticles. The new model is validated with a high number of experimental data of nanofluids containing water as the base fluid at the different types of nanoparticles, temperatures, and concentrations of nanoparticles available in the literature. The nanofluids contain Al2O3, SiO2, TiO2, GQD (graphene quantum dot), and CuO nanoparticles. Results of the new model were compared with experimental data and five other empirical models available in the literature, and absolute average relative deviation (AARD) between experiment and the results of the new model was obtained as 22.02 % which is acceptable and better than the previously reported models.
