The Ergun equation, shown below, is used to describe the flow of a fluid through a packed bed. ? P is the pressure drop, p is the density of the fluid, G_o is the mass velocity (mass flow rate divided by cross-sectional area), D p is the diameter of the particles within the bed, ? is the fluid viscosity, L is the length of the bed, and ? is the void fraction of the bed.

Given the parameter values listed below, find the void fraction ε of thebed.
