ABSTRACT:
The pressure drop and, hence, the flow through the holes in the peripheral walls of irrigation tubing can be increased without increasing the cross-sectional area of such holes by using non-round holes instead of conventional cylindrical holes. Preferred results when the non-round holes have a star shaped cross-sectional configuration defined by flexible fingers.
