spray heads
Spray Heads

Technical Information – operating pressure, flow, radius of throw, and nozzle options

  • Fixed head
  • Rotary Motor-driven
  • Rotary Impact
  • Bubbles
sprinkler irrigation
Sprinkler Irrigation

Uniform application by overlapping non-uniform wetting paterns

  • Sprinkler spray heads – no moving parts - small area – pop up
  • Microsprays – overhead – small area
  • Rotary Sprinklers – Impact or gear driven
technical information
Technical Information
  • Nozzle - removable – controls velocity and flow
  • Operating Pressure – inc pressure – inc water flow and change wetting pattern
  • Radius of Throw – furthest point
  • Water Distribution Patterns
  • Trajectory – angle
slide10

When a sprinkler is tested to determine its Distribution Rate Curve (often abbreviated as DRC)

One measure used to compare DRCs is the scheduling coefficient or SC.

slide11

Scheduling Coefficient (SC) is the average depth of water in the catch cans divided by the depth of water in the catch can having the least amount of water. Interpolation

  • Define Boundary
  • Select Spacing Pattern
  • Wind speed
  • Design coefficient
  • Select Sprinkler Head
  • Spacing based on nozzle and pressure
  • Precipitation rate
  • Time of application P t = depth needed
spacing
S less than or equal to k D = k 2 r

k is a constant depending on spacing and wind speed

Spacing
precipitation rates
Precipitation Rates

P = q/A

Units MUST be consistent. For:

P = precipitation rate (in/hr)

q =flow onto area (gal/min)

A = area (ft²)

P = 96.3 q/A
