摘要
本文对低压管道输水灌溉环状管网的经济性进行了分析研究,得出对集中轮灌的井灌区,在一定条件下环状管网优于树状管网的结论,推导出单环和双环管网流量分配系数公式和经济管径的通用计算公式。
Having analysed the economic cost of circular pipe network tor irrigation with low-pressure pipe to transfer water, the author cowhides that under some conditions circular pipe network is better than non-circular pipe network for concentrate rotation irrigation in well irrigation areas,And puts forward a formula of distributive coeficent for one circle and double circies and a universal formula of calculation economic pipe size.
