تأثير التباعد بين المرشات في انتظام الرش

In this research, the effect of spacing among sprinklers on sprinkling uniformity has been studied using four types of sprinklers, locally available and widely in use. The spacing among sprinklers, which gives a good uniformity and its relation to actual sprinkling radius as well as the applied intensity have been determined. The uniformity of sprinkling was determined using the relations of uniformity coefficient and distribution uniformity. The ratio of actual sprinkling radius, at almost zero wind speed, to sprinkling radius, without rotary of the head of sprinklers, in closed hall was determined. Obtained value for this ratio was about 0.75 for suitable operation pressures. It was found that the best setting of sprinklers for sprinkling uniformity is triangle. The square setting comes after and the last one is rectangle.
