The adding solid nanoparticles to liquids are significant topics to enhance heat transfer for many industrial applications in the last ten years. This article included the friction factor and forced convection heat transfer of SiO2 nanoparticle suspended to water as a base fluid into a car radiator experimentally. Four different concentrations of nanofluids in the range of 1 to 4vol. % have been used. The flow rate changed in the range of 1 to 5 LPM to get Reynolds number with the range of 250 to 2000. The results showed that the friction factor decreases with an increase in flowrate and increase with increasing in volume concentration. Furthermore, the inlet temperature to the radiator has insignificantly affected to the friction factor. Likewise, the heat transfer increases with increasing in flowrate, nanofluid volume concentration and inlet temperature. Meanwhile, application of SiO2 nanofluid with low concentrations can enhance heat transfer rate up to 30% as a comparison with pure water. The experimental results compared with the investigators experimental data, and there is a good agreement.
