◉ Friction Loss
Answer: Pressure loss due to friction as water flows through parts.


Rougher means more friction loss.


◉ Hydraulics
Answer: 1. Study of mechanical properties of fluid in motion or rest.
2. Calculation of pressure losses & irrigation system requirements.


◉ Matched Precipitation Rate (MPR)
Answer: When all heads in a zone produce similar precipitation
rates regardless of their arc.


i.e. With MPR, a 4 gpm full nozzle will put out 2 gpm on a half nozzle
and 1 gpm on a quarter nozzle. Each quarter section receives the

◉ Pressure Rating
Answer: Method of controlling the wall thickness of pipe so all pipe
in a class have the same pressure rating.


◉ Pressure Regulator
Answer: Mechanical device to lower the water pressure on
downstream side.


◉ PSI
Answer: Pounds per square inch
