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)

•  Crucial to determine pressure losses in

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

Friction Loss in Pipe 1.  Velocity – 5fps in PE; 7fps in PVC 2.  Inside Diameter (i. d.) – smaller creates more psi loss due to increased turbulence 3.  Roughness – “C” rating of pipe 4.  Length

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.

Zoning Rules – “Like With Like” • 

Flow limits maximum zone size

• 

Physical dimensions

• 

Shrubs & turf = different water needs

• 

Sun & shade areas = different water needs

• 

Fewest zones possible to minimize costs

Zoning Rules – “Like With Like” • 

Rotors with Rotors

• 

Fixed with Fixed

• 

Drip with Drip

• 

Easier to design and schedule

• 

Better calculations for water distribution, precipitation rates, etc.

Zoning Rules – “Like With Like”

Zoning Rules – “Like With Like”

• 

Runoff on sloped vs. flat areas

• 

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
