Abstract This study used an experimental setup consisting of a flat tube with louvered finned crossflow configuration to examine the effects utilizing ZnO-TiO 2 -water hybrid nanofluid on heat transfer rate, coefficient, Nusselt number, and pressure drop. The studies were carried out under laminar flow conditions (200 < Re 800), at four different temperatures (50, 60, 70, 80 °C), volume concentrations nanoparticles (0.025, 0.05, 0.1, 0.2%), three rates (4, 6, 8 LPM). findings compared pure water (0%). results indicate that using improves performance increases loss in comparison water. When comparing water, largest drop 87.8%, 21.7%, 26.4%, 10%, respectively. In addition, it was found that, up specific value (0.05%), increasing nanoparticle concentration enhanced coefficient but which began decrease past this value. Therefore, concluded greater than 0.05% negatively affect current operating conditions. maximum number obtained LPM °C inlet temperature, concentration.
