. • PRESSURE DISTRIBUTIUN SYSTEM <br /> 1. Select number of perForated laterals [-� <br /> 2. Select perforation spacing 3.0 <br /> 3. Since perforations should not be placed closer than 1 ft to the edge of the rock layer, <br /> subtract 2 feet from the rock I�yer lengih. <br /> 50 minus 2 feet = 48 feet <br /> 4. Determine the number of spaces between perForations. Divide the lengtl� above <br /> by the perforation spacing and round down to the nearest whole number. <br /> 48.0 divided 3.0 equals 'i�.0 spaces rounded do�vn = 16 <br /> 5_ Number of petforations is equal to 1 p#us the number of perforated spaces in step 4. <br /> 16 spaces pius 1 = 17 perforations per iateral <br /> 6. Multiply the pertorations per iateral by the number of laterals <br /> to get total number of perforations. <br /> 17 X 3 equals 51 total numbe� of perfora�ons <br /> 7. Determine the required flow rate by multiplying the number of <br /> perforations by the required perforations discharge from the table below. <br /> 51 perforations X 0.56 hole discharge = 29 gpm <br /> MAX(MUM NUp�ER OF�UARTER INCH PERFORATIONS PER REQUIRED PEFtFORATION D13CFbRRt�E <br /> tATERAL TO GUARlWTEE<1096 DISCHAROE VARIATION 1N G�AL.LONS PER MNUTE GPM <br /> PEFiF SPA�CIIrG IN FEET 1.25 IN PPf'E 1.5 IN PIPE 2A IN PfPE DISC.HFAD 7/32 IN PE 1!4 IN PERF <br /> 2,5 14 18 28 1.0 a Q.58 0.74 <br /> 3.0 13 17 26 2.0 b 0.8 1.04 <br /> 3.3 12 16 25 a USEt7 FOR SINC;LE FAMIIY HOA�S <br /> I 4.0 11 15 23 l b, USED FOR ALL OTHER APPlICATION <br /> 5.0 10 run 22 <br /> 8.
