Calculate Contour Loading Rate: Bed Width X Design Media Loading Rate <br /> �� ftZ X 1.2 GPD/ftZ = 12•0 gal/ft Can not exceed Tabte 1 <br /> D. Calculate Minimum Dispersal Bed Length: Dispersal Bed Area = Bed Width =Bed Length <br /> b30 ft2 : 10.0 ft = 63.0 ft <br /> 3. ABSORPTION AREA SIZING <br /> A. Catculate Absorption Width: Bed Width X Mound Absorption Ratio =Absorption Width <br /> 10.0 ft X 2.0 = 20.Q ft <br /> B. For slopes>196, the Absorption Width is measured downhitt from the upslope edge of the Bed. <br /> Calculate Downslope Absorption Width: Absorption Width - Bed Width <br /> 20.0 ft - 10.0 ft = 10.0 ft <br /> .
