Maximum suggested for delivery to a drop box of a home system is 2,71X1 <br />gallons per hour (45 gpm) to prevent build-up of pressure in drop box. <br />Treasure Distribution <br />3. a. Select number of perforated laterals _ <br />b. Select perforation spacing = ft. <br />c. Subtract 2 ft. from the rock layer length. <br />-3,-2ft. = ft. <br />d. Determine the number of spaces between perforations. <br />Length perf. spacing = ft. + _ ft. = spaces <br />e. spaces + 1 =perf4rations/lateral <br />L Multiply perforations per lateral by number of Wends to <br />get total number of perforations. <br />W=. x = perforations. <br />g r-= x VWTr-.I _- gpm. <br />SELECTED PUMP CAPACITY � gpm <br />S.
