Absorption Rate - ANS The rate or speed at which soil will accept water.
Absorption Rate is also known as __________or _________ rate. - ANS Percolation or
infiltration Rate
Actual Head Pressure - ANS The operating pressure measured at the base of the sprinkler
head.
Actual Pressure = _____________ - _____________ - ANS Static Pressure - Total
Pressure Losses
Actual Head Pressure has to be _______ or _______ to Minimum Head Pressure - ANS >
or =
Design Pressure = - ANS MHP + TPL
Design Pressure ( DP) must be _______ or _______ to Static Pressure. - ANS < or =
The pressure of water when it is not moving measured in PSI. - ANS Static Pressure
Water Hammer - ANS A shock wave in the piping system usually created by excessive flow
velocity and a fast closing valve.
The speed at which water travels through the piping system. Usually measured in fps. - ANS
Velocity of water
The generally accepted maximum velocity of water in PVC or Poly pipe is - ANS 5 FPS
The generally accepted maximum velocity of water in copper is - ANS 9 FPS
Transpiration - ANS the emission of water vapor from the leaves of plants.
Swing Joint - ANS A flexible joint or pipe connecting a sprinkler head to a pipe. Intended to
prevent damage to the head due to heavy foot traffic, etc. also used to raise or lower sprinklers
to final grade.
, A measure of the rate of change of elevation over a prescribed distance. May be expressed as
a ratio, a grade or as a percent. - ANS Slope
formula to calculate slope - ANS rise/run
Two most common types for sprinkler head spacing are - ANS Square and triangular
Spray Heads - ANS Sprinkler heads that throw a uniform sheet of water in a fixed or
adjustable pattern.
Species Factor - ANS Coefficient, reflecting plant species, used to adjust the reference
evapotranspiration.
solvent welding - ANS The act of chemically fusing pipe and fittings together using solvent.
Incorrectly referred to as "gluing".
The force of water in the piping system measured in PSI - ANS Water Pressure
Zone - ANS The group of sprinklers that are controlled by the same valve. Also referred to
as a section, station or circuit.
Working pressure - ANS The pressure left over in an irrigation system when all the
pressure losses are subtracted from the static pressure. Also called dynamic pressure.
Water that is not moving. - ANS Static water
Solenoid - ANS The electromagnet which is located on the valve, connected directly to the
controller, and initiates the opening and closing of the valve.
MPR means - ANS Matched precipitation rate
Define MPR - ANS Means all sprinkler heads within a watering zone will produce similar
precipitation rates, regardless of the pattern (or arc) they cover.
Master Valve - ANS An automatic or manual valve installed at the supply point which
controls water flow into the main line piping.
The weight of water is _______ lbs/gal. - ANS 8.3
3 types of copper pipe - ANS M, L, and K
Of the 3 types of copper pipe which has the heaviest wall thickness. - ANS K
