27 28 The simulation of center-pivot performance has been the subject of research 29 efforts since the 1960s. Center-pivot models frequently use empirical equations 30 relating pressure and sprinkler radial application pattern. Individual, stationary 31 water application patterns are overlapped and the resulting water application is 32 mapped in the field. Such models use constant tower angular...

This paper reports on the Response Time Index (RTI) of sprinkler heads. The standard plunge test has been carried out in a hot wind tunnel, which is similar to the one developed at the Fire Research Station, United Kingdom. Some of the modifications have been finished in this wind tunnel for the higher accuracy purpose. About 37 liquid-in glass sprinkler heads are studied including the pendent ...
