3. The formula for flow through a randomly packed bed of spheres is given by Ergun's equation Др 150д(1 - с)?и,, 1.75 (1- €)ри? H zP Where : Ap is the pressure drop across the bed, H is the length of the bed d is the equivalent spherical diameter of the packing, pis the density of fluid, u is the dynamic viscosity of the fluid, lo is the superficial velocity e is the void fraction of the bed Using dimensional analysis (MLT), show that this equation is either valid or invalid in any system of units. Explain. 3. The formula for flow through a randomly packed bed of spheres is given by Ergun's equation Др 150д(1 - с)?и,, 1.75 (1- €)ри?
