Figure 6.
The image features a scatter plot illustrating the relationship between actual energy consumption and calculated energy consumption, both measured in megajoules per kilogram. The horizontal axis represents calculated energy consumption, ranging from 0 to 2 megajoules per kilogram, while the vertical axis shows actual energy consumption over the same range. Data points are depicted in blue, forming a trend that suggests a strong positive correlation, with a dotted line indicating the regression line. The R squared value is presented as R squared equals 0 point 9 7 8 7, suggesting high correlation between the two variables.Comparison of actual energy consumption with calculated model predictions
