We calculate the rangeRof a rotating water sprinkler as a function of the angles ϑ,φ specifying the orientation of the nozzles, the mass rate of water ejection, and the area of the orifice of the nozzles. In order to compare the two approaches, we solve the problem completely in both a laboratory and a rotating frame of reference. We discuss advantages and disadvantages presented by each reference frame in solving the problem. We displayR(ϑ,φ) in three‐dimensional plots, treating water ejection rate and nozzle orifice area as fixed parameters.
