Abstract

The impact of two parameters - the pressure regulator X1 at the nozzle and the speed of the machine X2 for the amount of water flow through the sprinkler (Y, mm) experiment were determined by 8 mm diameter nozzles. The experiment was carried out in the laboratory of “Design of Irrigation and Equipment” used by “Sprinkler’s uniformity distribution measuring equipment” at the School of Engineering and Technology of MULS. In order to determine the rain intensity of low pressure sprinkler nozzle, mathematical statistical methods was used and it was found that the maximum amount of water supplied by the sprinkler nozzle is 1.727 mm/min with a maximum pressure of 30 PSI and a minimum speed is 1 m / min with a minimum flow rate of 0.313 mm/min. At a pressure regulator value of 20 PSI, the speed was a maximum of 3 m/min.

Highlights

The impact of two parameters - the pressure regulator X1 at the nozzle and the speed of the machine X2 for the amount of water flow through the sprinkler (Y, mm) experiment were determined by 8 mm diameter nozzles
The efficiency of sprinkler irrigation can be enhanced by ensuring uniform distribution of water supplied by area, and by determining the quaesitum of sprinkler nozzles, uniform distribution of water supplied by irrigation machines, and water evaporation losses [4,5,6]
Irrigation water intensity (Y, mm/min) depending on the two technological parameters, the water pressure from the nozzle and the speed of irrigation machine, the coded phase expression of the equation was determined in the following manner

Summary

Introduction

The impact of two parameters - the pressure regulator X1 at the nozzle and the speed of the machine X2 for the amount of water flow through the sprinkler (Y, mm) experiment were determined by 8 mm diameter nozzles. Many technical and technological works have been carried out since 2004 designed at restoring irrigated agriculture in the country as part of the state policy, At the end of 2019, Mongolia had 57.1 thousand hectares of lands for irrigation, of which 54.1 thousand hectares were irrigated. This accounts for 12.5 per cent of the country’s total arable land. 92.0 per cent of all the farmers in the country irrigate their fields by simple methods, 7.1 per cent use sprinkler equipment for irrigation, and the level of mechanization has reached 32.2 per cent.
