In the present study, the rheological behavior analysis was conducted on a water-based nanofluid containing reduced graphene oxide nanoparticles. The analysis was performed in the concentration range of 1.0–5.0 {mg/ml} and shear rates of 12.23, 24.46, 36.69, 61.15, 73.38, and 122.3 {s−1} at 25–50°C. (257)
