| dc.description.abstract | Irrigation system performance assessment is of high priority in irrigation research to solve the problem of irrigation development & management. It is obvious that many irrigation systems are performing below their capacity. This situation may lead to non-uniform and unreliable water distribution. The performance assessment alone is not sufficient to evaluate an irrigation system, so to present a true image, a cost estimation of the system is also done, which includes both capital investment & working cost. The mini sprinkler systems recently introduced for irrigation needs to be evaluated for their performance. A mini sprinkler system was evaluated for its hydraulic performance. Experiment was conducted to evaluate the hydraulic performance using a mini sprinkler system having 'double nozzle - full circle sprinkler at various sprinkler spacings (8m x 8m, 10m x 10m and 12m x 12m) at three operating pressures (1.0, 1.5 and 2.0 kg/cm ). The index of jet break up was obtained in all the three operating pressures in the range of 2.63 to 4.65, however ideal value of index of jet break up was obtained close to 4.0 at 1.5 kg/cm^. Uniformity coefficient for all the system arrangements was in the range of 79.14% to 87.68%. The uniformity coefficients were obtained at par for 8m x 8m spacing at 2.0 kg/cm^ and 10m x 10m spacing at 1.5 kg/cm^. Cost analysis shows that the annual cost of all the systems ranges from Rs. 13663 to Rs. 20729. The spacing of 10m x 10m at operating pressure of 1.5 kg/cm^ showed better hydraulic performance with economical feasibility. | en_US |
