Recommended va(ue is 4-71 ft z per perforation. <br /> Does not app(y to At-Grades <br /> a. Bed Areo = Bed Width (ft) X Bed Length (ft) <br /> 10 ft X 63 ft = 630 ftZ <br /> b. Square Foot per Perforation = Bed Area divided by the Tota(Number of Perforations. <br /> 630 ftz .- 63 perforations = 10.0 ft2/perforations <br /> 13. Select Minimum Average HeQd: 1.0 ft <br /> 14. Select Perforvtion Discharge (GPM) based on Table: 0.56 GPM per Perforation <br /> �5• Determine required Flow Rote by multiplying the Tota!Number of Aerfs. by the Perforation Dischorge. <br /> b3 Perfs X 0.56 GPM per Perforation = 36 GPM <br /> 16.
