Texas Landscape Irrigation Exam
Questions and Answers 100%
Accurate
Pressure compensating devices help save water because they? - ANSWER-
Help eliminate misting or fogging at the sprinkler heads
Landscape Irrigation - ANSWER-The art and management of applying water
to landscape in a manner to encourage growth of plant material and support
water conservation
Irrigation sensors - ANSWER-(Measure rain, wind, soil moisture, and freeze)
that save water and eliminate liability issues concerning ice related
accidents during freeing weather
Pressure Regulation Device - ANSWER-Devices which eliminate misting or
fogging at the sprinkler heads, thus achieving better uniformity and saving
water
,Hydrozoning - ANSWER-The practice of zoning an irrigation system based on
similar plant material with similar watering reguirements due to
environmental and or geographic influences including, but not limited to, soil
type, slope, site orientation, and solar radiation
Licensed landscape irrigators - ANSWER-Responsibility to educate, promote,
support and practice water conservation in the landscape irrigation industry
in order to preserve one of out most precious resources on earth
Absorption Rate - ANSWER-The speed at which water can penetrate or
infiltrate the soil
Actual Head Pressure - ANSWER-The operating pressure measured at the
base of a sprinkler head.
Actual head pressure formula - ANSWER-(Static pressure) - (Total pressure
lost) = Actual head pressure
Bushing - ANSWER-The pipe fitting used to change an irrigation component
to a larger or smaller size
,C-factor - ANSWER-Rating the smoothness inside of the pipe - higher the
factor translates to more smoothness
Check Valve - ANSWER-A valve that allows flow in one direction only
air gap - ANSWER-an approved Air gap is the unobstructed vertical distance
through free atmosphere between the lowest point of a water supply outlet
and the flood level rim of the fixture or assembly into which the outlet
discharges. Physical seperation must be at least twice the diameter of the
water supply outlet but never less than 1"
Most common air gap? - ANSWER-Kitchen sink
Application Rate (Precipitation rate) - ANSWER-Rate at which water is applied
by sprinkler heads in a certain pattern.
For irrigation contractors, water conservation starts with? - ANSWER-A great
design
, Three methods to evaluate application rate - ANSWER-Densogram,
Precipitation rate formulas, Water audit
The proper watering time is early morning because? - ANSWER-Sprinkler
patterns are generally less distorted from the wind
Automatic control valve - ANSWER-An electrical or hydraulic remote control
valve in a sprinkler system which is activated by an automatic controller
Backflow - ANSWER-An unwanted reversal of the flow of water in a piping
system which can potentially allow non-potable water to pollute or
contaminate the potable water supply.
arc - ANSWER-Degrees of coverage of a sprinkler from one side of a pattern
to the other
The art and management of applying water to the landscape to encourage
the growth of plant material and support water conservation is? - ANSWER-
