12. (20 points) (A). What is the head loss when a single-media sand (ρs=2.65 g/cm3) filter is fluidized? The initial media depth is 1.5 m, and the porosity before fluidization is 0.35. (B). At steady state, it was observed that the sand bed was expanded to 3 m deep, what is the porosity of this expanded bed? What is the head loss in this expanded bed?
