Firstly the mean volume of each grade was calculated from the mean mass and the ball density given in Table 1. Using the equations for the volume and surface area of a sphere, the mean radius of the balls can be calculated and thus the mean surface area. The mass loss per unit of surface area in mg per mm2 per hour can then be calculated.
