Irrigation第 12 / 100 题
Distribution uniformity (DU) in an irrigation audit measures what?
a.The color of the turf
b.The total gallons used per month
c.The pipe pressure rating
d.How evenly water is applied across the irrigated area
解析
Distribution uniformity describes how evenly water is spread across a zone, comparing the driest areas to the average application. Higher DU means less water waste because you do not have to over-irrigate to compensate for dry spots. Poor uniformity commonly comes from mismatched heads, wrong spacing, or pressure problems.
