-This is usually a screen in the faucet outlet.When the waters leaves the faucet there are air spaces where the water has to go around the wires in the screen.Then as the water travels down the skin effect(the nature of a liquid to stick together) takes over and draws the water back together‚eliminating the space cause by the screen.The water from the faucet increases the speed because of acceleration due to gravity.The formula for flow rate is:cross-sectional

The calculations for colligative properties do not depend on the identity of a substance that is being used because only the amount of the substance that is used plays a role. The types of calculations that are colligative properties are: freezing point of depression‚ boiling point elevation‚ vapor pressure lowering‚ and osmotic pressure.1 Colligative properties are present in everyday life‚ such as adding salt to a boiling pot of water. By adding salt to the water‚ the boiling point of elevation

Engineering materials Choice of materials for a machine element depends very much on its properties‚ cost‚ availability and such other factors. It is therefore important to have some idea of the common engineering materials and their properties before learning the details of design procedure. Common engineering materials are normally classified as metals and nonmetals. Metals may conveniently be divided into ferrous and non-ferrous metals. Important ferrous metals for the present purpose
