Development of regression equation for heat capacity and density of nanofluids properties

This research focused on the development of regression equation for nanofluids properties. Nanofluid is the mixing fluid with the nanoparticles size material with effective properties to increase the heat transfer process in such cooling system. This is because base fluid such as water and ethylene...
