Hydraulic performance of sprinkler installations

Fire Technology, 1967
Some 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

1995
Over 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, 1969
The 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 ...

Hydraulic Performance of Step Aerator

Journal of Hydraulic Engineering, 2008
The 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 ...

Performance of Hydraulic Gas Compressors

Journal of Fluids Engineering, 1976
A hydraulic gas compressor has no moving parts and compresses gas at the expense of hydraulic energy by means of entrainment in a downward moving column of liquid with subsequent separation of gas and liquid at depth. Documentation is cited giving the history and performance data for large hydraulic air compressors built around 1900.

Reactive Barriers: Hydraulic Performance and Design Enhancements

Groundwater, 2004
Abstract The remediation of contaminated ground water is a multibillion‐dollar global industry. Permeable reactive barriers (PRBs) are one of the leading technologies being developed in the search for alternatives to the pump‐and‐treat method.
