Surface Area and Volume Modeling of the Williams Pear (Pyrus Communis)

Two methods for estimation of the surface area and volume of a Williams pear quarter provides the focus of this study. The heat energy needed for the drying process depends, in part, on the surface area. The first method involved multiplying the number of pears by the average surface area or volume. The second method involved calculating the surface area and volume of each pear quarter based on the pear length only, as described in the proposed algorithm. It was based on significant correlation between pear length and points on the upper bounder of the pear as well as on integral calculus.
