Analytical Approach for Direct Drip Lateral Hydraulic Calculation

Abstract

In application of previous analytical approaches for drip lateral hydraulic computation, it is generally assumed that the emitter outflow along the lateral is constant. This basic assumption may cause significant errors in hydraulic computation. In this present paper an accurate analytical approach is developed. In the suggested analysis the emitter outflow is considered to be variable along the lateral. The proposed method is demonstrated over a practical range of variation of drip irrigation parameters. A comparison test indicated that the suggested analytical approach produces results that follows closely the accurate numerical solution.
