in this article, the elasto-plastic analysis of thick walled fg tanks subjected to internal pressure is elaborated. today, thick walled tanks containing liquids with high pressure are used in the chemical industries. the high internal pressure causes part of the thickness of reservoir to yield; therefore, we need the elasto-plastic analysis. in this study, elasto-plastic behavior of fg cylindri...

The distribution of daily requirement of water in multi-storeyed semi-urban residential buildings in India involves pumping from the ground level to a reservoir at the top, and gravity feed to all levels below. String diagrams bring out the scope for reduction of unnecessary movement of water. A modified storage arrangement is proposed resulting in a small saving in energy required for water di...

The study assessed the quality of water obtainable in six (6) storage tanks present male and female hostels on Federal University Dutse campus. Physicochemical analyses; temperature, pH, turbidity, electrical conductivity, nitrate, phosphate were conducted using standard methods. Presumptive, confirmed, completed tests employed to determine total fecal coliforms from samples most probable numbe...

As implementation of the Ballast Water Convention draws nearer a major challenge is the development of protocols which accurately assess compliance with the D-2 Standard. Many factors affect the accuracy of assessment: e.g. large volume of ballast water, the shape, size and number of ballast tanks and the heterogeneous distribution of organisms within tanks. These factors hinder efforts to obta...

Household water in Oman, as well as in other countries in the region, is stored in tanks placed on house roofs that can be subjected to physicochemical factors which can promote microbial growth, including pathogens and opportunistic pathogens which pose health risks. Water samples were collected from 30 houses in a heavily populated suburb of Muscat. The tanks used were either glass reinforced...

Studies were carried out on the localization and mapping of gas stations in the urban area of São Carlos city, for an environmental diagnosis related to soil, surface water and underground water contamination resulting from likely leaking in fuel underground storage tanks. Considering that a provision of legal restriction makes it possible that most of public areas are not located in gas statio...

Energy use in water supply systems represents a significant portion of the global energy consumption. The electricity consumption due to the water pumping represents the highest proportion of the energy costs in these systems. This paper presents several comparative studies of energy efficiency in water distribution systems considering distinct configurations of the networks and also considers ...
