TCEQ IRRIGATION LICENSE STUDY
GUIDE
BPA requirements for fertilizer injection machine - ANS-Reduced Pressure Principle Assembly
(RPPA) (RPZ) is required when fertilizer injection are being used.
Causes backsiphonage? - ANS-Caused by a negative or Sub-atmospheric stress. Example-City
departments are the usage of fire hydrant or there's a city most important line spoil, or a person
sucking liquid from a tumbler the use of a straw.
Causes of leaking take a look at valve - ANS-Debris-can enter the valve. (Can use Y strainer to
offer an answer.)
characteristics of waft vs strain for given pipe length - ANS-as flow increases stress decreases
velocity will increase
characteristics of looped irrigation foremost strains - ANS-1/2 flow gymnasium by using 1/2 pipe
> low strain, loss downsize pipe, both at the identical time.
Characteristics of water - ANS-non compress-able, potable, non potable
Common units of measure for go with the flow fee in panorama irrigation - ANS-(GPM, gallons
per minute) (GPH,Gallons according to hour), (IPH, Inches in keeping with hour)
Conversion of psi to ft (head) of water - ANS-1' = .433 PSI
2.31'= 1 PSI
Definition of move-connection? - ANS-Any real or ability connection between a potable water
deliver and any source of infection or pollution.
Definition of layout stress - ANS-
Definition of design strain - ANS-Water in motion
Definition of excessive-threat device? - ANS-Non-potable water, chemical substances, fertilizers
Degree of hazard - ANS-A degree of the diploma of threat or damage to the general public's
fitness.
