Laboratory Test Program of Rotary Plate Sprinklers
… • Wetted diameter - reduced pressure sprinklers have smaller wetted diameters, resulting in higher application rates that are likely to exceed soil infiltration rates with resulting runoff.<br> • Droplet size - mean drop size is related to the nozzle diameter and discharge pressure, …

Prediction of water droplet behaviour during fire extinguishment
Sprinklers have been used in fire suppression for about 100 years. Even though their design has changed from simple perforated pipes to sophisticated automatic systems of mist and sprinkler nozzles, still they play the same role - they dramatically reduce death and injuries due to fire, as well as …

Collector size effect on the measurement of applied water depth from irrigation systems
… without specially considering the low pressure sprinklers now commonly used on center pivot systems; the recommended collectors may not accurately measure the applied depth from these sprinklers. The collector size effect on measured water depth and measured depth variability was studied for …

The influence of the Critical Zone on hillslope hydrology and stability
… controls. Simulations of both controlled sprinklers and natural storm events revealed that the presence of a deep, irregularly weathered bedrock layer controls subsurface storage, groundwater movements, and localized pressure build-up, improving the agreement between simulated and observed …

Epidemiological studies on primary inoculum of Venturia inaequalis and V. asperata for apple scab management
… layer, with more spores detected above the sprinklers than below. Based on these results, since ascospores could settle on susceptible apple tissues, it is essential to ensure a rain-free period of at least 24 hours post-irrigation to prevent scab infections. The primary infection season of …

Impact of high-rise morphology on gas temperatures during fires
… etc, and "active" approach e.g. Sprinklers etc. Considering thediversity of building morphologies of modern high-rises buildings made possible byimproved construction techniques and materials, this research investigates thepossibility of the building morphology becoming an …
