This document provides a sprinkler layout and specifications for an irrigation field consisting of 3 units labeled A, B, and C. The main pipeline runs through all 3 units for a total length of 800 + 400 + 400 = 1600 meters. Sprinklers are spaced 39.62 meters apart along the lateral lines with 20 sets of 18 sprinklers each. The sprinklers have a diameter of 50.6 meters and are Rainbird 80 EHD nozzles with an 11/32 inch diameter operating at 70 psi to provide a radius of 50.6 meters. Water is supplied by a pump that operates at 105.62 horsepower with a flow rate of 29.2 gallons per minute and 87% efficiency to provide a total dynamic head
