Irrigation第 15 / 100 题
A matched precipitation rate (MPR) nozzle set is designed to do what?
a.Apply water at the same rate regardless of arc (quarter, half, full)
b.Increase pressure at each head
c.Reduce the number of valves needed
d.Eliminate the need for a controller
解析
Matched precipitation rate nozzles apply the same depth of water per hour whether the head covers a quarter, half, or full circle. Manufacturers scale each nozzle's flow to its arc so a quarter head uses about one-fourth the flow of a full head. This keeps the whole zone evenly watered on a single run time.
