喷灌管道的沿程水头损失,乃是喷灌系统水力学中值得探讨的问题之一。计算喷灌管道沿程水头损失的多口系数F的数值,取决于管道上孔口的数目,随着孔口数目的增加,F相应减小。一般计算的通用公式为:
Sprinkler pipe along the head loss, but sprinkler irrigation system is worth studying one of the problems. The numerical value of the multi-port coefficient F for calculating the head loss along the sprinkler pipe depends on the number of ports in the pipe. As the number of ports increases, F decreases accordingly. General calculation of the general formula is:
