CIT - Certified Irrigation Technician Irrigation Principles and Components Questions and Answers

Question 1

An irrigation technician measures the water pressure at a hose bibb before the system is turned on and gets a reading of 65 PSI.
After the zone with the highest flow is activated, the pressure is measured again at the same point and reads 50 PSI.
What is the 50 PSI reading called?

Accepted Answer

Dynamic pressure

Answer

Friction loss

Answer

Static pressure

Answer

Surge pressure

Question 2

A client's irrigation system is causing a fine mist to come from the spray heads, leading to poor water distribution and significant waste from wind drift. Which of the following is the MOST likely cause of this issue?

Accepted Answer

High water pressure

Answer

Low water pressure

Answer

Clogged sprinkler nozzles

Answer

A partially closed master valve

Question 3

What is the primary function of a backflow prevention device in an irrigation system?

Accepted Answer

To prevent contamination of the potable water supply.

Answer

To increase water pressure for better sprinkler coverage.

Answer

To filter out debris and sediment from the water supply.

Answer

To regulate the flow rate to individual irrigation zones.

Question 4

A technician needs to calculate the precipitation rate for a sprinkler zone to program the controller correctly. Which formula is commonly used for this calculation?

Accepted Answer

PR = (GPM x 96.3) / Area

Answer

PR = (Area x 96.3) / GPM

Answer

PR = (GPM x Area) / 96.3

Answer

PR = GPM / (Area x 96.3)

Question 5

While performing system maintenance, a technician notices that one entire zone of rotor heads is not operating, while all other zones function correctly. The controller indicates the zone is active. Which of the following is the LEAST likely cause of this specific problem?

Accepted Answer

A broken mainline pipe before the zone valve

Answer

A faulty zone valve solenoid

Answer

A cut in the field wiring to that specific zone

Answer

A malfunctioning diaphragm in the zone valve

Question 6

Which of the following components is essential for connecting a sprinkler head to a lateral line while providing flexibility and protection against damage from mowers or foot traffic?

Accepted Answer

Swing joint assembly

Answer

Reducer bushing

Answer

Gate valve

Answer

Pressure regulator
