Recommended value is 4-11 ft 2 per perforotion. <br /> Does not appl y to At-Grcdes <br /> a. 8ed Area = Bed Width (ft) X Bed Length (ft) <br /> 10 ft X 63 ft = 630 ft� <br /> b. Squore Foot per Perforation = Bed Area divided by the 7otal Number of Perforations. <br /> 630 ftZ - 63 perforations = 10.0 ft2lperforations <br /> 13. Select Minimum Averoge HeQd: 1.0 ft <br /> 14. Select Perforetion Discharge (GPM) based vn Table: 0.56 GPM per Perforation <br /> �5• Determine required Ftow Rate by multiplying the Total Number of Perfs. by the Perforation Distharge. <br /> 63 Perfs X 0.56 GPM per Perforation = 36 GPM <br /> 16.
