How do I work out how many litres per minute can be injected under pressure into the main irrigation line?
Set up your injection unit and run the irrigation system. Inject water into the main irrigation line to help determine how many litres per minute can be injected into the system while it is running.
This is trial and error and may take some time to fine tune.
For example, your mainline pressure is 550 kilopascals and your injection unit operates at 700 kilopascals, injecting 300 litres in 30 minutes.
