Figure 6: Relative error versus flow velocity for bentonite concentration of 0.1 – 1.0 vol%.
In this study, a total of 160 sample data were taken from experiments in a range of flow velocity (0 -1.2~1.5 m/s) and bentonite concentration (0.1-1.0 % volume). The machine learning models went under training. About 62% of the data were used for training, and the remaining 38% were used for testing.
