PUMP SELECTION PROCEDURE
A. Determine pump capacity:

1. Minimum suggested is 20 gpm
2. Maximum suggested is 45 gpm Perforation Discharges in GPM
Pressure Distibution Head Perforation diameter

3. a. Select number of perforated laterals 7/32 1/4
b. Select perforation spacing= feet. 1.oa o.56 0.74
c. Subtract 2 ft. from the rock layer length. 1.5 0.69 0.90
Rotk layer length
-2 ft. = feet. 2.ob o.So 1.04
d. Determine the number of spaces between perforations. a Use�.o foot single homes.
Length perf.spacing= ft.= ft. = spaces b Use 2.0 feet for anything else.
e. spaces+ 1 = perforations/lateral
f. Multiply perforations per lateral by number of laterals to
get total number of perforations. �e� 5 x �r s,�e T = perforations.
