TEXAS IRRIGATION LICENSE EXAM 2024 ACTUAL EXAM
COMPLETE 150 QUESTIONS WITH DETAILED VERIFIED ANSWERS
(100% CORRECT ANSWERS) / ALREADY GRADED A+
Hydraulic Design Steps - (answers)1. Layout heads
2. Head inventory
3. Group in Zones
--Determine limiting gpm from WM & service line
4. Layout Pipe
心的坚强决定了我们的命运。当
--Put valve in middle & closer to side with less gpm to make the critical head calculations easier.
我们面对挫折时，是一颗不屈的
心让我们勇敢前行
5. Size pipe
--Start at a dead end.
--Work towards the water source.
--Don't size a pipe unless everything downstream has been sized.
--Make mainlines 1" or larger
6. Check Critical Head
--L. F. D. 100. I. A. (Ladies Fall Down 100x In Abeline)
--Length of pipe, Flow, Diameter of pipe, pressure loss per 100', Item loss, Accumulated loss
--LFD. Use Design
--100. Uses Reference Charts
--I. Use #s from LFD & 100 for Item loss.
--A. Add losses from I.
, --Other Equations. Use DP (Design Pressure) & AHP (Actual Head Pressure) to determine if the
zone works.
7. Schedule
--Determine precipitation rate
C-Factor - (answers)Rating of the smoothness of the inside of the pipe.
Higher C-factor = smoother
PVC is 150. Copper is 140.
Generally decreases over time meaning the pipe gets rougher and more friction loss.

Densogram - (answers)Graphic view of precipitation to check uniformity.
心让我们勇敢前行
Higher rates are darker.
Distribution Uniformity (DU) - (answers)Uniformity of distribution of water over a given area as
a %.
Found by doing a catch can test.
Closer to 100% is better with 75%-80% excellent, 65%-75% good and <65% poor.
Dynamic Water - (answers)Water in motion
Dynamic Pressure (Working Pressure) - (answers)Pressure of water in motion.
