    1. Lawn Sprinkler design Group 3: Seong Won Byun Jakob Combs Zachary Lightner Bart Sudhoff Devin Templeton

    2. Objective Provide 1 inch of water to an area of 13,460ft2 in the shortest time Least amount of water falling outside the property Minimize cost of materials Minimize electric utility costs

    3. Layout

    4. Layout Large area used 30-foot radius sprinkler heads Smaller areas used combination of 18 and 17-foot radius sprinkler heads

    5. Layout Sprinkler head locations Circles are 30-foot radius Outside corners are 270° rotors Corners and boundary edges are 90° and 180° rotors All others are 360° rotors

    6. Pipe Layout & AFT Model

    7. Sprinkler Parameters Pressure difference across the component is [Equation 1] The k-loss value is [Equation 2]

    8. Table 2: Required Flow Rate and Time to Water for Each Zone

    9. Cost Analysis

    10. Cost Analysis Largest cost in the project is the rotor sprinkler heads. Another major factor for cost is the diameter of pipe.

    11. Summary Project Outcomes: 56 Sprinkler Heads Total Material Cost: $1154 192 Minutes to Water
