hmmm. ok

The drip line is "rated" at 2 litres per hour per "dripspot" they are spaced at 20 cm, so 3 per meter. That's 6 litres per hour per metre. A 10 km system is 10,000 metre @ 6 litres per hour per metre. That's 60,000 litres per hour, or 1000 litres per minute or roughly 250 gallons per minute.

What if I run 3" pipe? Will that flow that much water?

Btw...apologies to OP for hijacking his thread. I could start my own thread, but it looked like he had solved his problems.

Guess my "edit time" is up.

Miscalculation. 5 drippers per metre, not 3.

!00,000 litres per hour. 1666 litres per minute. 416 gallons per minute. Yikes. Now am looking at 6" pipe and a pump that'll flow that much water.

Right??


No. It's 4 drippers per metre. No. It's 5....I'm going to bed.

Still too much general info and not enough specifics.

If you really want assistance you should supply the following I advised earlier and we can get a better idea on the in's and out's.

Data needed is a dimensioned lay-out of the system. ) this won't change flow rates but will influence pressure needed

Pipe lines sizes also shown on the system lay-out ) Ditto above.

Number of drippers on each leg or run of drip line

any change in elevation from water supply to the highest point in your system
