Abstract
Expressions are developed and presented for the pressure head available at any point within a trickle irrigation subunit. Histograms are drawn showing the distributions of pressure within typical subunits. Distributions of emitter flow rates within typical subunits are derived from considerations of the effects of pressure differentials and manufacturing variations in emitter characteristics. The coefficient of emitter manufacturing variation is shown to be a significant design consideration. The equations and distributions developed are used to complete tables giving the emission uniformity and efficiency of systems for various combinations of design and equipment characteristics.
