Abstract


Model for calculating the quantity of water that evaporated during oven drying of Otamiri clay has been derived. The model; j = exp ((In1/2.9206)18) showed that the quantity of water that evaporated during the drying process was dependent on the drying time, the evaporation surface being constant. It was found that the validity of the model is rooted in equation (1), where both sides of the equation were correspondingly almost equal. The respective deviation of the model-predicted quantity of evaporated water from the corresponding experimental value was less than 26%, which is quite within the acceptable deviation range of experimental results, hence depicting the usefulness of the model.

Keywords: Model, water, evaporation, drying, clay
