1. Pipe Sizing Chart Exercise Based upon the tables in the book Rain Bird Irrigation Design Manual

2. Pipe Sizing Chart Exercise Irrigation pipe carries water from point to point Some pipes are under constant pressure Some pipes are under pressure only when a valve is open

3. Pipe Sizing Chart Exercise Main line - carries water to water meter – under constant pressure Service line – carries water from meter to residence, valves, etc. – under constant pressure Lateral line – carries water from valve to the sprinkler – under pressure only when valve is open

4. Pipe Sizing Chart Exercise Pipe types are selected based on type of use Pipe sizes are based on what? Flows

5. Pipe Sizing Chart Exercise Main and service lines Class 315 — 1/2” and 1-1/2” and larger Schedule 40 — 3/4” to 1-1/4” Common abbreviations: Class = CL Schedule = SCH

6. Pipe Sizing Chart Exercise Lateral lines Class 315 — 1/2” Class 200 — 3/4” and larger Class = CL Schedule = SCH

7. Pipe Sizing Chart Exercise With that in mind... And using the pipe sizing tables... Pipe sizes are selected based on flow Without exceeding safe velocity

8. Pipe Sizing Chart Exercise Build a table showing: Flow ranges Pipe sizes Pipe types

9. Pipe Sizing Chart Exercise Create a table for main/service lines and lateral lines with the above information From the Rain Bird Irrigation Design Manual Sch 40 technical data table Cl 200 technical data table Cl 315 technical data table
