description abstract | Drip irrigation may need to be installed in situations in which there is not enough energy to operate the emitters under optimum performance conditions. This paper characterizes the head-discharge functional form of a pressure-compensated (PC) and non-pressure-compensating (NPC) drip emitter operating under low pressures. It also analyzes the statistical relationship between manufacturing and hydraulic variations of low-pressure operating emitters assuming that both are independent random variables. A hydraulic simulation methodology was implemented to predict the effect of emitter manufacturing and hydraulic variations on irrigation uniformity while working under a range of operating pressures. The manufacturing variation of PC and NPC emitters was evaluated with the Monte Carlo method for a single horizontal drip line with different pressure heads and different numbers of emitters evenly spaced. The coefficient of manufacturing variation ( | |
