WebSand and anthracite for filters are rated by effective particle size and uniformity. The effective size is such that approximately 10% of the total grains by weight are smaller and … WebThe pressure difference across the sand bed is assumed to be the head of water since atmospheric pressure acts on top of the water and at the bottom of the bed. First convert the head into pressure difference. ∆p = ρg(h2– h1) = {0 – (998 x 9.81 x 0.12)} = -1174.8 Pa. The length of the bed (L) is 120 mm.
