The experimental apparatus was composed of a water circulation system, an air supply system, a test section and a measurement system~ Air and water were used as working fluids. . The test section was a vertical rectangular channel of 10mmxlOOmmx700mm made of Plexiglas as shown in Fig.l. The measuremen.t system consisted of the UVP and a personal computer to record and treat data. Water was fed ...

Unexpected shortage of water supply is common phenomena especially in dense population such as in hostels. Water supply at the students’ hostels is usually drawn from tank at the roof top of the building. Apparently there is no early warning system to monitor the tank water level when it has reached the critical level. The situation worsened when there is no personnel or technician in-charge to...

molecular isolation of biodegradable mycobacteria from water supplies of iranian hospitals background and objectives: some microorganisms, mainly members of two genera including pseudomonas and mycobacterium , were found to be capable of transforming and degrading of polluting agents. we herein report the isolation of a few mycobacteria with the ability to biodegrade organic and inorganic compo...

This paper summarises the impact of major earthquakes, 2010–2011, on Christchurch’s water supply network and what recovery measures have been applied, what worked well, what did not and why. A number of issues related to the open nature of the Christchurch water supply network were identified during earthquakes. It was difficult to manage large water supply pressure zones during the post-earthq...

The study was focused on variability in discharges on equity of water distribution of outlets along the secondary canal. Hydraulic performance was evaluated based on delivery performance ratio (DPR), adequacy based on relative water supply (RWS) and variability in discharges using coefficient of variation (CVs). Off take and all outlets were calibrated by area velocity method. During study peri...

Today, the main quality criterion in production of fiberboards is a uniform supply mixed wood fiber slurry to mesh part press using high pressure headbox. The interaction water, various inclusions waste wood-fiber semi-finished product, as well stainless steel provokes occurrence chemical reactions that cause intense corrosive destruction working parts inlet. At present, study corrosion inlet s...
