The aim of the present study is to investigate the dynamic viscosity of the Mg(OH)2-ethylene glycol(EG) nanofluid in different solid concentrations and temperatures. The nanoparticles with the average diameter of 10 nm are used in this study. Using two-step method, the nanoparticles were suspended in ethylene glycol as a base fluid. A new correlation for predicting the dynamic viscosity of the nanofluid is proposed based on the solid concentrations and temperatures. It can be interesting to note that at lower temperatures, this increase is more noticeable than those in higher temperatures.
