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
