Improvement of Thermal Processes for Using Residues from Bioethanol and Sugar Production in Brazil: Experiments and Proposed Optimization Measures

Table 2

Overview of equations for the mean particle size.

Equation 5	surface partial
Equation 6	volume partial
Equation 7	specific surface area

where = area of the particles [mm²]; = mean particle size [mm]; V = volume [mm³]; and = specific surface area [mm⁻¹].
