A dual media filter contains 0.4 m of sand with effective size 0.55 mm and 1.4 m of anthracite with effective size 1.2 mm. The sand and anthracite have density of 2650 kg/m³ and 1700 kg/m³, respectively. The filtration rate is 10 m/h, and the design temperature is 10 C (p = 999.7 kg/m³, μ = 1.31 x 10-3 kg/m-s). Determine the head loss (m) through the filter. Use the Ergun equation and the midpoint Ergun parameters for sand (ky = 112, k; = 2.2, & = 0.42) and anthracite (ky = 228, k; = 4.4, ε = 50%).
