The pressure drop through a particle bed can be used to determine the external surface area and the average particle size. Data for a bed of crushed ore particles show Δp/L = 84 (lbf/in.2)/ft for airflow at a superficial velocity of 0.015 f is. The measured void fraction is 0.47, and the estimated sphericity Φs is 0.7. Calculate the average particle size and the surface area per unit mass if the solid has a density of 4.1 g/cm3. How sensitive is the answer to an error of 0.01 in ε?
