  • Meyer Screw Pump provides extended valve life

    A New Jersey based asphalt company approached Wm. W. Meyer & Sons seeking a solution to an issue they were having with a competitor’s airlock ability to hold a seal. The valve was lined with ceramic tiles and was supposed to have a one-year lifetime in that particular system. Unfortunately, the asphalt company realized the valves were only lasting 5-6 months at the most. The limited ...

  • Valves in Water System of Heating Air Condition

    Common valves in water system of heating air condition include gate valve, globe valve and butterfly valve.   Gate vale For its moderate length, rotary adjusting rod and good regulating performance, gate valve is widely utilized in large caliber pipes.   Globe valve Globe valve is suitable for small caliber pipes for its long length, ...

  • A real-time, rapid emergency control model for sudden water pollution accidents in long-distance water transfer projects

    A real-time, rapid emergency control (EC) model is proposed to cope with sudden water pollution accidents in long-distance water transfer projects. The EC model outputs the method of EC based on pollutant properties. A generalized form of EC model is proposed and tested with a demonstrative project. The rapid prediction formulas of emergency control parameters (ECPs) are proposed under ...

  • Modelling of suspended sediment in a weir reach using EFDC model

    Construction of hydraulic structures often leads to alteration of river dynamics and water quality. Suspended solids entering the upstream of the weir cause adverse effects to the hydroecological system and, therefore, it is necessary to build a modelling system to predict the changes in the river characteristics for proper water quality management. In this study, the discharges and total ...

  • Contribution to a flood situation management: a supervisory control scheme to reduce disaster impact

    Inundations due to river overflows are becoming more frequent; management of flood is thus an important task belonging to the set of preventive measures allowing the protection of people and goods downstream. The flood situation management method proposed in this paper was designed to reduce the flood impact at its early arising stage. The river is supposed to be equipped with reservoirs in ...

  • Interaction between the US Army Corps of Engineers and the Orleans Levee Board preceding the drainage canal wall failures and catastrophic flooding of New Orleans in 2005

    The authors hope to correct any premature conclusions about the role of the pre-Katrina Orleans Levee Board (OLB) in the failure of the outfall drainage canals in New Orleans during the 2005 hurricane – conclusions that appear to have been based on inaccurate information and/or assumptions. With regard to the 17th Street and London Avenue Canals, the authors have not uncovered any ...

  • Dual-use value of network partitioning for water system management and protection from malicious contamination

    This paper considers the introduction of a contaminant into a water supply system using a backflow attack. The recent development of techniques for water network sectorization, aimed at improving the management of water systems, is also an efficient way to protect networks from intentional contamination and to reduce the risk of the dangerous effects of network contamination. Users can be ...

  • A comparison between different techniques for water network sectorization

    Water network partitioning represents one of the best methodologies for improving water balance and pressure control of a water distribution system in order to reduce water leakage. These techniques can be applied with greater effectiveness defining a smaller permanent network district, called a District Meter Area (DMA), achieved by the insertion of gate valves and flow meters. If the DMAs are ...

  • Rotary batch mixer yields high-quality blends for powder metallurgy

    GKN Sinter Metals Inc. is the world's largest manufacturer of parts made by powder metallurgy, a molding process that produces complex shapes with a range of properties. Powder metallurgy offers benefits in part fabrication over competing metal processes. It is faster than forging or casting and permits the use of more performance-enhancing alloys than die-casting. GKN Sinter Metals, Auburn ...

  • Spatial and historic characteristics of Phnom Penh central area: Railway Station Garden

    Phnom Penh was subject to westernisation during colonisation. Constructions of European styles and great public works sequentially proceeded to transform the city. Ancient canal dating to 1413 was restored enclosing French city for flood prevention and leaving locals outside. Not until 1899 did then urbanism orient to localisation and the canal was developed for a green-space. Semantically, this ...

  • Hydrodynamic modelling of a regulated Mediterranean coastal lagoon, the Albufera of Valencia (Spain)

    Coastal lagoon hydrodynamics are strongly influenced by sea water exchange, especially when the connection between the lagoon and the sea is artificially regulated. These situations increase the complexity of the hydrodynamic regime, requiring the use of numerical models to understand their behaviour. Traditionally, one-dimensional models have been used, although in recent years, the development ...

  • Free-surface flow simulations for discharge-based operation of hydraulic structure gates

    We combine non-hydrostatic flow simulations of the free surface with a discharge model based on elementary gate flow equations for decision support in the operation of hydraulic structure gates. A water level-based gate control used in most of today's general practice does not take into account the fact that gate operation scenarios producing similar total discharged volumes and similar ...
