Design Tools for Small AFOs

This spreadsheet design tool is used to assist the Sprinkler Vegetative Treatment System  engineer in determining the flow rate, pipeline friction losses, elevation losses, pump capacity, and required horsepower for the pump station. This tool also evaluates the water flow characteristics in the towable sprinkler  system.  Here individual nozzle performance is evaluated along with tube friction loss and water velocity.
