Table 2: Calculation of r, based on the loss on drying value.
Description Range (a) Range (b) Range (c)
Range of values Range value interval 0 to 2 3 to 10 2 to 3
Radius (r) range to apply 0 to 10 5 to 0 10 to 0
Symbol Rmax Radius top value 10 5 10
Vmax Range top value 2 10 3
Vmin Range minimum value 0 3 2
V Experimental value V V V
Equations r = Radius value calculated r = (RmaxV)/(Vmax) r = (Rmax(Vmax-V))/ (Vmax- Vmin) r = (Rmax(Vmax-V))/ (Vmax- Vmin)
