Divide the Length of Lcrterals by the Perforvtion Spacing <br /> and round down to the nearest whole number. <br /> Number of Perforotion Spnces 30 ft = �ft = 10 Spaces <br /> Number of Perforat3ons per L.atera! is equal to 1.0 plus the Number of Perforat9on Spates. Check table <br /> 8, below to verify the number of perforatians per lateral guarantees less than a 109b discharge variation.
