Many features of nanofluids, such as the Prandtl number and viscosity, are researched as the number of studies conducted in the field of nanofluids increases. Observations on the Prandtl number and viscosity of titanium oxide nanofluids are made in this study. These observations are made at low concentrations of titanium oxide nanoparticles and temperatures ranging from 30.4°C to 70.4°C. Novel correlations for viscosity and Prandtl number as functions of temperature have been developed and compared to the previously published models for Prandtl number and viscosity. The results indicate that titanium oxide-ethylene glycol nanofluid has a greater viscosity and Prandtl number than all other titanium oxide nanofluids observed in the study at 0.01 nanoparticle concentration. The results on viscosity and Prandtl number for the new correlations fall within the same range as those found in the literature, indicating that the new correlations introduced as functions of temperature in this study can be used in future research to establish viscosity and Prandtl number calculations for the different types of nanofluids at specific temperatures.
