TCEQ IRRIGATION LICENSE STUDY
GUIDE
BPA necessities for fertilizer injection machine - ANS-Reduced Pressure Principle Assembly
(RPPA) (RPZ) is needed when fertilizer injection are being used.
Causes backsiphonage? - ANS-Caused with the aid of a poor or Sub-atmospheric pressure.
Example-City departments are the usage of fire hydrant or there is a town fundamental line
smash, or a person sucking liquid from a pitcher using a straw.
Causes of leaking check valve - ANS-Debris-can input the valve. (Can use Y strainer to offer a
solution.)
characteristics of waft vs stress for given pipe length - ANS-as go with the flow will increase
stress decreases pace increases
traits of looped irrigation major strains - ANS-half of float fitness center by means of half of pipe
> low stress, loss downsize pipe, each at the identical time.
Characteristics of water - ANS-non compress-in a position, potable, non potable
Common gadgets of degree for float rate in landscape irrigation - ANS-(GPM, gallons in line
with minute) (GPH,Gallons per hour), (IPH, Inches in step with hour)
Conversion of psi to feet (head) of water - ANS-1' = .433 PSI
2.31'= 1 PSI
Definition of move-connection? - ANS-Any real or ability connection among a potable water
supply and any supply of infection or pollutants.
Definition of layout stress - ANS-
Definition of design strain - ANS-Water in movement
Definition of excessive-risk system? - ANS-Non-potable water, chemical substances, fertilizers
Degree of hazard - ANS-A measure of the degree of threat or harm to the general public's
fitness.
