development and performance evaluation of pressurized irrigation system

Abstract EN

The purpose of the present study is to develop and evaluate a sprinkler irrigation system based on its design criteria to minimize friction loss, pressure head variation, and specific energy and maximize water uniformity distribution.

The system was developed from single inlet open lateral (SIOL) to double inlet closed lateral (DICL).

Experiments were conducted to study two different parameters (lateral length and irrigation water inlet method to lateral line) affecting the performance of the developed system.

The system performance was evaluated in terms of water distribution uniformity, coefficient of uniformity, pressure head variation and specific energy.

It was concluded that pressure head variation and specific energy were significantly decreased while water distribution uniformity was improved with DICL compared to SIOL at all lateral lengths.

The lateral length of 165m with DICL was recommended to be used as they achieved acceptable distribution uniformity, coefficient of uniformity and pressure head variation values which were 75%, 81% and 18%, respectively.
