Hydraulic Performance Evaluation: Investigation of Mini - Sprinkler Irrigation System - Softcover

Inhaltsangabe

The mini sprinkler method of irrigation is recently introduced pressurized irrigation method. The basic objective of mini sprinkler is to simulate rainfall and to apply uniform water to crop. The performance of mini-sprinkler is judged by its uniformity of distribution of water which depends on the proper, efficient and economic design of the system. The important parameter in mini sprinkler irrigation is to optimize the spacing between mini sprinklers for different crops which influences the discharge, uniformity and cost. Considering the aspects and complexity in the management of mini sprinkler irrigation system, present investigation is planned to generate information on the distribution profile, precipitation characteristics and hydraulic performance of mini sprinklers. Thus overall finding reveals that, coefficient of uniformity increases with pressure from 2 to 3 kg cm-2 and then decreases with pressure from 3 to 4 kg cm-2. Accordingly, contour graph results, more uniform distribution with 3.0 kg cm-2 operating pressure as compared to all other operating pressures.
