Hydraulic performance of sprinkler installations
Fire Technology, 1967Some sprinkler system designers place total reliance upon rules and pipe schedules, while others take an opposing view by insisting that every system should be calculated. The authors suggest a middle ground approach that offers economic advantages, but does not significantly alter system performance.

Hydraulic Performance and Rehabilitation Strategies
1995Over the past twenty years a major financial effort has been made to improve the water supply in Portugal. A significant evolution can be observed, with 77% of the population currently connected to public systems and a target of 95% by the year 2000. Supplying a high percentage of the population is however not sufficient by itself.

Hydraulic Performance of Penstock Trifurcations
Journal of the Power Division, 1969The pressure distributions and the energy losses were obtained in an air tunnel for the following penstock trifurcations: a two-wye arrangement, two types of plug-funnel proposal, and an abrupt junction. Published results of other types of trifurcation, namely, the one provided with a tie bar, and other wyes have been also included in this report in ...

Fish guidance structures: hydraulic performance and fish guidance efficiencies
, 2020The hydraulic performance and fish guidance efficiency (FGE) for behaviourally-based mechanical fish guidance structures, i.e. louvers and modified angled bar racks (MBRs), were evaluated experimentally and the results are presented herein.

Hydraulic Performance of Step Aerator
Journal of Hydraulic Engineering, 2008The step aerator for stepped chutes was recently introduced. Its purpose is to preaerate the zone between the spillway crest and the point of incipient bottom aeration to counter cavitation damage for relatively large unit discharges. The shape of the step aerator is optimized herein by hydraulic modeling to design the air supply and to indicate the ...
