摘  要:
In this paper,a determining method for frictional head loss of micro-sprinkling hose is put forward and equipment for testing micro-sprinkling hose flow and pressure is designed.Moreover,the corresponding test methods and evaluation index for frictional head loss are proposed and a more scientific empirical formula for calculating frictional head loss for micro-sprinkling hose is obtained through regression analysis of testing data.
