| Abstract: | In this paper, a mathematical model of the sprinkling system on grassland is set up, and the efficiency of the system when the sprinkling radiuses of sprinklers are discretionary is studied. It is proved that the maximum efficiency of the system is 18311π≈ 90.2%. This result is better than that the maximum efficiency 332π≈82.7 % of the sprinkling system given by Jiao Ying. |
