    O.K. guys take it easy on me! I want to gravity feed a drip line to 20 trees for the purpose of delivering systemic pesticide. Do you irrigation guys think I'll get even flow at each point down the line?

    As long as your supply is elevated high enough, it could work.

    A 1 in2, 12" long column of water exerts .433 psi at the base. Using RB as an example, the beginning of an operating pressure for a drip emitter is 15psi which would require the water source to be 34.5' in the air. As far as the uniform flow, you would be best off to use a pressure compensating drip emitter, which works from 10 to 50 psi. Hope this helps :waving:
