Hydraulics Irrigation Systems: The Dos & Don’ts
• Hydraulics – study of behavior of fluids at rest (static) and in motion (dynamic) • Relationships between flow (gpm), velocity (fps), and pressure (psi)

pipe, fittings, valves, etc.
Static Pressure – water at rest • Created by elevation change or pump • A column of water 1 ft high = 0.433 psi • Every 1 ft elevation change = change of 0.433 psi
Dynamic Pressure – water in motion • Always find static psi losses or gains first • Then dynamic psi losses due to movement • Friction loss occurs due to turbulence
• Pushing water up hill, subtract 0.433 psi • Water going downhill, add 0.433 psi
created by moving water • 4 factors affect friction losses in pipe

5 Major Components
1. Controller
1. Controller – brain of the system
• Types of controllers:
2. Valves – muscles of the system
1. Electromechanical
3. Backflow Prevention Devices (BFPD) 4. Pipe
2. Hybrid 3. Central Control • Tech. constantly changing; stay up-to-date
5. Heads (fixed, rotors, drip, etc.)
1. Controller • Two methods of providing signal: A. Hydraulic – water pressure controls valve via small-diameter tubing B. Electrical – voltage along wires; most common
2. Valves • Used b/c not enough water to run everything at one time • Open & close by signal from controller • Valves buried under ground in plastic valve boxes – USE THEM
2. Valves – Two Types 1. Hydraulic, Normally Open • Small water tube from controller to valve • Water under pressure = valve closed • Controller allows psi to drop = valve open • Good for dirty water systems • Hole in tube = valve stays on
2
2. Valves – Two Types 2. Electric, Normally Closed: • Controller sends ≈ 24V to solenoid on valve – lifts plunger off to open port. • Water psi on top of diaphragm drops – valve opens • Wire problems = valve won’t open
3. BFPD • Systems are not air- or water-tight • Irrigation water considered contaminated • Fertilizers and pesticides • Contaminate domestic supply • All systems must have BFPD
4. Pipe • PVC (main & laterals) • Rigid, installed by trenching • Slip fittings; primer + “glue” • Polyethylene (small mains & laterals) • Flexible, installed with a puller • Barbed fittings; clamps Copper – Service line; plumber install?
5. Heads – Fixed / Sprays • 75% DU = excellent; 60% DU = good • 30 psi – optimum psi for most heads • High PR (1 – 2.5”/hr); use short cycles • Strip nozzles – narrow turf strips • Flood heads – small spaces, single plants • Nozzles easily interchanged
3
5. Heads – Fixed / Sprays •
5. Heads – Fixed or Rotor?
Fixed Nozzles = 15’ to 17’ max radius
•
Rotating Nozzles = 8’ to 30’ radius
Heads – Spray Patterns (Arcs)
5. Heads - Rotors • 80% DU = excellent; 70% DU = good
•
Full circle (360°)
•
•
Half circle (180°)– edges, borders, etc.
•
Quarter circle (90°)
•
Mid-size Rotor = 15’ to 30’ radius Rotor = 25’ to 40’ radius
•
Corners
•
Most Rotors - less distance covered than ½ or full due to less water; space accordingly
Heads – Spray Patterns (Trajectories) •
Standard – 30º to 40º above horizontal
•
Low or flat – 10º to 15º
•
High – Greater than 40º
•
Variable Arc Nozzles (VANs) - 1º to 360º
•
Rotors – use those that allow arc adjustments
5. Heads – Micro Irrigation • Drip, micro sprays, bubblers • FILTERS!
4
Distribution Curves
5. Heads • Repair Tips: • Dont dig up 1st – can be repaired from top
A = 314 ft2 (6%)
• Filter – always check for clogging
B = 942 ft2 (19%)
• Don’t stomp on head if leaking
C = 1571 ft2 (31%)
• Check for recall from distributor
D = 2199 ft2 (44%)
• Don’t adjust the diffuser screw too much!
Overlap Determination •
Most heads have triangular shaped distribution curves
Overlap Determination •
Manufacturer specs = max allowable spacing
•
This is a reference number only
•
It applies to dead calm situations & should not be used in an actual design
• •
Always anticipate a minimum 4 MPH wind when spacing heads
Head to Head = Even distribution of water (DU) & balanced precipitation rates (PR)
Overlap Determination •
You can increase or decrease spacing of fixed
Precipitation Rates •
heads 1 foot and rotors by 3 feet •
•
PR - speed at which an amount of water is applied
Distribution uniformity (DU) – goal when
•
Used to estimate run times
performing head layout in design
•
Used to prevent wet or dry areas
Don’t want wet or dry spots
•
If not known – usually over watering occurs
5
Precipitation Rates •
Rates vary according to sprinkler type:
Precipitation Rates •
High PR = runoff on soils with low IR
•
Use shorter cycles: •
Decreased runoff
•
Decreased chance for erosion
Precipitation Rates •
•
Total run time limited by total GPM available at
is 30 GPM
the source •
•
Fewer valves per acre
•
Fewer controller stations per acre
•
Distribution Uniformity (DU) measures how evenly water is applied
•
Sprinkler designed to operate well at a given radius
•
Adjust too much = DU reduced = dry spots
•
PR is avg amount of water over an area
•
Does not account for DU
1 zone @ 30 min
Radius Adjustment and DU •
2 zones @ 15 min ea
Low PR systems cost less: •
Water supply
Radius Adjustment and DU •
Fixed Spray Heads: •
Adjustment screw changes radius and internally changes GPM Adjustment screw radius and GPM are adjusted here, before water leaves the nozzle
6
Radius Adjustment and DU •
Radius Adjustment and DU •
Rotors and Impact Heads: •
NEVER reduce radius of spray on rotors to less than 75% of manufacturer’s radius
Adjustment screw, flap, or pin externally •
disrupts spray radius w/o change in GPM
Example: 33 ft. x 75% = 24.75 ft.

PSI loss on sloped vs. flat areas
Winterization Tips • Usually by Nov 1st • BFPD most critical: • Exposed to elements • Leave valve at 45º • Fully open or closed allows moisture accumulation
9
Winterization Tips • Blowing out system: • Compressed air • Never exceed 60 psi – damage or melt • Close BFPD – don’t forget 45º afterwards • Farthest zone 1st • Never more than 5 minutes = melt rotors

• Hydraulics – study of behavior of fluids at rest (static) and in motion (dynamic) • Relationships between flow (gpm), velocity (fps), and pressure (psi)

pipe, fittings, valves, etc.
Static Pressure – water at rest • Created by elevation change or pump • A column of water 1 ft high = 0.433 psi • Every 1 ft elevation change = change of 0.433 psi
Dynamic Pressure – water in motion • Always find static psi losses or gains first • Then dynamic psi losses due to movement • Friction loss occurs due to turbulence
• Pushing water up hill, subtract 0.433 psi • Water going downhill, add 0.433 psi
created by moving water • 4 factors affect friction losses in pipe

5 Major Components
1. Controller
1. Controller – brain of the system
• Types of controllers:
2. Valves – muscles of the system
1. Electromechanical
3. Backflow Prevention Devices (BFPD) 4. Pipe
2. Hybrid 3. Central Control • Tech. constantly changing; stay up-to-date
5. Heads (fixed, rotors, drip, etc.)
1. Controller • Two methods of providing signal: A. Hydraulic – water pressure controls valve via small-diameter tubing B. Electrical – voltage along wires; most common
2. Valves • Used b/c not enough water to run everything at one time • Open & close by signal from controller • Valves buried under ground in plastic valve boxes – USE THEM
2. Valves – Two Types 1. Hydraulic, Normally Open • Small water tube from controller to valve • Water under pressure = valve closed • Controller allows psi to drop = valve open • Good for dirty water systems • Hole in tube = valve stays on
2
2. Valves – Two Types 2. Electric, Normally Closed: • Controller sends ≈ 24V to solenoid on valve – lifts plunger off to open port. • Water psi on top of diaphragm drops – valve opens • Wire problems = valve won’t open
3. BFPD • Systems are not air- or water-tight • Irrigation water considered contaminated • Fertilizers and pesticides • Contaminate domestic supply • All systems must have BFPD
4. Pipe • PVC (main & laterals) • Rigid, installed by trenching • Slip fittings; primer + “glue” • Polyethylene (small mains & laterals) • Flexible, installed with a puller • Barbed fittings; clamps Copper – Service line; plumber install?
5. Heads – Fixed / Sprays • 75% DU = excellent; 60% DU = good • 30 psi – optimum psi for most heads • High PR (1 – 2.5”/hr); use short cycles • Strip nozzles – narrow turf strips • Flood heads – small spaces, single plants • Nozzles easily interchanged
3
5. Heads – Fixed / Sprays •
5. Heads – Fixed or Rotor?
Fixed Nozzles = 15’ to 17’ max radius
•
Rotating Nozzles = 8’ to 30’ radius
Heads – Spray Patterns (Arcs)
5. Heads - Rotors • 80% DU = excellent; 70% DU = good
•
Full circle (360°)
•
•
Half circle (180°)– edges, borders, etc.
•
Quarter circle (90°)
•
Mid-size Rotor = 15’ to 30’ radius Rotor = 25’ to 40’ radius
•
Corners
•
Most Rotors - less distance covered than ½ or full due to less water; space accordingly
Heads – Spray Patterns (Trajectories) •
Standard – 30º to 40º above horizontal
•
Low or flat – 10º to 15º
•
High – Greater than 40º
•
Variable Arc Nozzles (VANs) - 1º to 360º
•
Rotors – use those that allow arc adjustments
5. Heads – Micro Irrigation • Drip, micro sprays, bubblers • FILTERS!
4
Distribution Curves
5. Heads • Repair Tips: • Dont dig up 1st – can be repaired from top
A = 314 ft2 (6%)
• Filter – always check for clogging
B = 942 ft2 (19%)
• Don’t stomp on head if leaking
C = 1571 ft2 (31%)
• Check for recall from distributor
D = 2199 ft2 (44%)
• Don’t adjust the diffuser screw too much!
Overlap Determination •
Most heads have triangular shaped distribution curves
Overlap Determination •
Manufacturer specs = max allowable spacing
•
This is a reference number only
•
It applies to dead calm situations & should not be used in an actual design
• •
Always anticipate a minimum 4 MPH wind when spacing heads
Head to Head = Even distribution of water (DU) & balanced precipitation rates (PR)
Overlap Determination •
You can increase or decrease spacing of fixed
Precipitation Rates •
heads 1 foot and rotors by 3 feet •
•
PR - speed at which an amount of water is applied
Distribution uniformity (DU) – goal when
•
Used to estimate run times
performing head layout in design
•
Used to prevent wet or dry areas
Don’t want wet or dry spots
•
If not known – usually over watering occurs
5
Precipitation Rates •
Rates vary according to sprinkler type:
Precipitation Rates •
High PR = runoff on soils with low IR
•
Use shorter cycles: •
Decreased runoff
•
Decreased chance for erosion
Precipitation Rates •
•
Total run time limited by total GPM available at
is 30 GPM
the source •
•
Fewer valves per acre
•
Fewer controller stations per acre
•
Distribution Uniformity (DU) measures how evenly water is applied
•
Sprinkler designed to operate well at a given radius
•
Adjust too much = DU reduced = dry spots
•
PR is avg amount of water over an area
•
Does not account for DU
1 zone @ 30 min
Radius Adjustment and DU •
2 zones @ 15 min ea
Low PR systems cost less: •
Water supply
Radius Adjustment and DU •
Fixed Spray Heads: •
Adjustment screw changes radius and internally changes GPM Adjustment screw radius and GPM are adjusted here, before water leaves the nozzle
6
Radius Adjustment and DU •
Radius Adjustment and DU •
Rotors and Impact Heads: •
NEVER reduce radius of spray on rotors to less than 75% of manufacturer’s radius
Adjustment screw, flap, or pin externally •
disrupts spray radius w/o change in GPM
Example: 33 ft. x 75% = 24.75 ft.
