abstract: there is always a need to increase a distillate output of solar still. if plates will be used inside solar still then distillate output of solar still are expected to increase. hence, an experimental study is conducted to improve distillate output of basin solar stills by increasing the effective surface area with the help of different plates. for the purpose of experiment, three sola...

INTRODUCTION Air pollution in confined environments is a serious health problem, in that most people spend long periods indoors (in homes, offices, classrooms etc.). Some people (children, the elderly, heart disease patients, asthmatic or allergic subjects) are at greater risk because of their conditions of frailty. The growing use of air-conditioning systems in many public and private building...

Brazing generally require cumbersome apparatus be it induction, vacuum or torch brazing. In torch brazing, metals are joined by using the oxyacetylene cylinder. It thus becomes difficult to carry out brazing at the places where it is not possible to take heavy gas cylinders and brazing apparatuses. So it is tried to figure out the method to carry out brazing at places where conventional brazing...

physical and mechanical properties of alfalfa (medicago sativa, l.) grind are required for optimum design of equipment used in transporting, processing and storage of the material. this study was conducted to determine the effect of particle size (2.38, 3.36 and 4.76 mm) and moisture content (8, 9.3 and 11% wb) on some physical and mechanical properties of alfalfa grind. these properties includ...

INTRODUCTION Silicates have been used by the drinking water utilities for decades (Shuldener and Sussman, 1960). Initially, silicates were used for “red” water complaints in the distribution system. Control of zinc [from galvanized iron] and aluminum corrosion by silicates has also been described by early researchers (Lehrman and Shuldener, 1951, 1952). More recently, silicates have been found ...

Abstract The coiling stable roll of hot-dip galvanized is a defect formed in the galvanizing process. zinc slags and floating foreign matters pot will directly or indirectly adhere to surface stabilizer with flow liquid. When strip steel contacts roll, slag extrude deform iron base plate form pits. In this paper. causes defects were analyzed. There two methods eliminate that is, reduce generati...

in order to provide the data needed for the design of saffron processing equipment, physical properties of its flower were investigated. these properties included dimensions, mass, true and bulk densities, porosity, static and dynamic coefficients of friction, and terminal velocity as a function of moisture content. the average range of these properties for the three different parts of saff...
