Pure water is neutral in nature with pH 7. Due to the presence of dissolved minerals in rain water, the pH increases and becomes alkaline. Alkalinity in water is due to the presence of hydroxide (OH), carbonate (CO3) and bicarbonate
The estimation of water hardness as applied to boiler water and other water is great interest for the chemical industry in general.the determination of water hardness has always been an especially important factor in the manufacturing control of sugar industry,
Eriochrome Black T is a complexometric indicator that is used in complexometric titrations, which is mainly used to determine total hardness of Water. In the below photo you can see that in its deprotonated form, Eriochrome Black T is blue. It turns red when
A Notch is regarded as an orifice with water level below its upper edge. Notch is made of a metallic plate and its use is to measure the discharge of liquids. These are used for measuring the flow of water
An orifice meter is a conduit and a restriction to create a pressure drop. An hour glass is a form of orifice. A nozzle, venturi or thin sharp edged orifice can be used as the flow restriction. In order to

When a ship heels, the centre of buoyancy of the ship moves laterally. It might also move up or down with respect to the water line. The point at which a vertical line through the heeled centre of buoyancy crosses
In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the
Coarse aggregates are particles greater than 4.75mm, but generally range between 9.5mm to 37.5mm in diameter. They can either be from Primary, Secondary or Recycled sources. Primary, or ‘virgin’, aggregates are either Land- or Marine-Won.Secondary aggregates are materials which are
