<p>An irrigation line having desired output flow characteristics therealong including a liquid flow conduit couplable to a source of liquid under pressure; a multiplicity of liquid discharge elements associated with the conduit along the length thereof and having their inputs coupled to the conduit at locations such that the flow rates of liquid through the individual discharge elements are in a desired proportional relationship. The individual capacities of the discharge elements may be varied as well.</p> |
