Comparative Performances Of Mechanized Water Spraying Systems: Single And Combined Frontal Ramps (swivel / Frontal)
Authors : Youssef M’sadak .
Abstract
The present investigation consists of diagnosing the field operation of a frontal ramp, a simple system of mechanized sprinkling of water, exploited in the governorate of Beja (North-West of Tunisia) and a combined ramp (pivot- Frontal) system, which ensures of these two modes of mechanized spraying, used in the governorate of Manouba (North of Tunisia), and to assess the quality of the watering carried out during their first harvest. This work has particularly affected the comparison of the rainfall distribution of the water and the coefficient of uniformity of each system with respect to the other as follows: single frontal ramp with combined frontal mode, in the wind speed ranges and Operating pressures relatives. The operating diagnosis showed that the two machines are in good condition and capable of achieving a good rainfall distribution (Cu > 85% in strong wind). The comparative performance study found that the simple front-end system is less sensitive to wind and less energy-demanding compared to the combined front-end mode. Certainly, the subsequent use of a simple mechanized sprinkler system is an adequate solution, considering also its good efficiency compared to a combined mechanized sprinkler system.
