A monomedia anthracite filter is designed with the following specifications: effective size 1.1 mm, uniformity coefficient 1.4, and density 1650 kg/m³. Calculate the percentage expansion that occurs at a backwash rate of 32 m/h at the minimum winter temperature of 3 C (p = 1000 kg/m³, u = 1.62 x 10-³ kg/m-s). Use the midpoint Ergun parameters for anthracite: ky = 228, k; = 4.4, EF = 50%.
