OSTP Pressure Distribution <br /> Desi n Worksheet UNIVERSITY � <br /> Minnesota Poliution ��•..,, "-� - <br /> Controi Agency � OF MINNESOTA '�-��.�' <br /> 12. Calculate the Square Feet per Perforotion. Recommended value is 4-11 ft Z per perforotion. <br /> Does not appl y to At-Grades <br /> a. Bed AreQ = Bed Width (ft) X Bed Length (ft) <br /> 10 ft X 63 ft = 630 ftz <br /> b. Square Foot per Perforation = Bed Areo divided by the Totat Number of Perforations. <br /> 630 ftz .- 63 perforations = 10.0 ftZ/perforations <br /> 13. Select Minimum Average Head: 1.0 ft <br /> 14. Setect Perforotion Discharge (GPM) based on Table: 0.56 GPM per Perforation <br /> 15. Determine required F(ow Rate by multiplying the Total Number of Perfs. by the Perforation Discharge. <br /> 63 Perfs X 0.56 GPM per Perforation = 36 GPM <br /> 16.
