The model based upon the Poiseiulle flow of hybrid nanofluid within a micro channel for the inclusion of varying viscosity and thermal conductivity. The suggested model is designed for the use of variable properties of the hybrid nanofluid embedding with the metal and oxide nanoparticles such as Cu and Al2O3 submerged in the base fluids i. e. https://www.ldartstudio.com/product-category/setting-sprays/
