An engineer has used uniformly sized solid graphite cylindrical pa of 0.32 ami to assemble a packed bed reector having a naight flows through t this loosely packed bed e the following holght of 30 dim. Then, saluret fat a mass now rate of 9000 kg/min per 1 m^2 and length 300 Kandber Pof cross-section arma. Estimate is the aquivalent surface a. What is e-to-volume diameter of the graphite particies? les? What is the equivalent volume spnare diameter of the graphite particles? What is the sphericity of the particies? d. Estimate th te the porosity of the packed bed. Use t Use the figure provided below, e. Use the Engun equation to determine the pressure drop across the packed bed.
