Sodium silicate is also the technical and common name for a mixture of such compounds, chiefly the metasilicate, also called waterglass, water glass, or liquid glass. The product has a wide variety of uses, including the formulation of cements , coatings, passive fire protection , textile and lumber processing, manufacture of refractory ...
Within this choice set, the preferred water tariff depends on multiple factors including: the goals of water pricing; the capacity of a water services supplier to allocate its costs, to price water, and to collect revenues from its customers; the price responsiveness of water consumers; and what is considered to be a fair or just water tariff.

Water sachets or sachet water is a common form of selling pre-filtered or sanitized water in plastic, heat sealed bags in parts of the global south, and are especially popular in Africa. [1] Water sachets are cheaper to produce than plastic bottles, and easier to transport. [2] In some countries, water vendors refer to sachet water as "pure water".
Small pack facilities (facilities that package water in containers between 8 oz. and 2.5 gallons) use the least amount of water (1.26 L per 1 L), followed by mixed packaging facilities (1.46 L per 1 L). Facilities that package water for home and office delivery in sizes of 2.5 gallons to 5 gallons use the most water (1.56 L per 1 L). [32]
Nigeria's largest city, Lagos state is surrounded by water from the sea and a lagoon. the total estimated percentage of clean water supply in the city is about 81.32%. [33] However, since the raw water in the lagoon is too polluted, the city gets its water from the Ogun and Owo rivers.
One litre is slightly larger than a US liquid quart and slightly less than an imperial quart or one US dry quart. A mnemonic for its volume relative to an imperial pint is "a litre of water's a pint and three-quarters"; this is very close, as a litre is about 1.76 imperial pints. A cubic foot has an exact volume of 28.316846592 litres.
Glass is a relatively heavy packing material and wine bottles use quite thick glass, so the tare weight of a full wine bottle is a relatively high proportion of its gross weight. The average weight of an empty 750 mL wine bottle is 500 g (and can range from 300 to 900 g), which makes the glass 40% of the total weight of the full bottle. [ 27 ]
The refractive index of liquid water (1.333 at 20 °C (68 °F)) is much higher than that of air (1.0), similar to those of alkanes and ethanol, but lower than those of glycerol (1.473), benzene (1.501), carbon disulfide (1.627), and common types of glass (1.4 to 1.6). The refraction index of ice (1.31) is lower than that of liquid water.
