    I have an area that is 110' long and 30' wide it will get planted with Blue Fescue every 16" to 18" apart.
    I will have a one inch supply line outlet 30' in from each end unregulated pressure is 85psi. I was going to reduce it to 40psi for drip lines at .4GPH for each plant.
    Can I do the entire area on one ZONE

    Thanks for any help

    With .4 GPH and 40psi what would the max number on emitters you would run?

    For that you would have to know how much gpm the 1" line can give you . I may get bashed here because i'm not doing any kind of math .. but If you designed it right - you could probably do 200-250 emitters.

    O.k, you can cram about 12 gpm +/- through 1" before exceeding the 5' per second rule. Once you find the gpm available, one of Boot's Dollar Store calculators will give you number of emitters available. Take into consideration plant type and shade/sun + soil and drainage.

    I could care less about what emitters might be in the truck. You tally up the number of plants and multiply by the number of emitters per plant, and divide that into the gpm you have.

    Slam dunk once you have your gpm/gph/psi figured out.
