Abstract/Contents:"Microirrigation can be an effective method of delivering water to plants from elevated tanks but the head incident to drip emitters may be significantly below that recommended by the emitter manufacturer to provide the specified flow rate (q). The objective of this study was to quantify the effect of variable pressure on q and water application uniformity (WAU) of selected drip emitters. Flow rate was measured at three different heads (3.5 ft., 5.5 ft., and 57.7 ft.) and WAU was calculated as 1 - cv where cv equaled the standard deviation divided by the mean q from eight replicates of each emitter. Mean q ranged from zero to 102% of manufacturer specified q (MSFR) at 5.5 ft. of head and from 95 to 193% of MSFR at 57.7 ft. WAU was greater than 0.90 for more than half the emitters at 5.5 ft. and for 75% of the emitters at 57.7 ft."
