Water Tanks
A water tank is a container for storing water, for many applications, drinking water, irrigation, fire suppression, farming, both for plants and livestock, chemical manufacturing, food preparation as well as many other uses. Water tank parameters include the general design of the tank, and choice of construction materials, linings. Various materials are used for making a water tank: plastics (polyethylene, polypropylene), fiberglass, concrete, stone, steel (welded or bolted, carbon, or stainless). Earthen pots, such as matki used in South Asia, can also be used for water storage. Water tanks are an efficient way to help developing countries to store clean water. History Throughout history, wood, ceramic and stone tanks have been used as water tanks. These containers were all naturally occurring and some man made and a few of these tanks are still in service. The Indus Valley civilization (3000–1500 BC) made use of granaries and water tanks. Medieval castles needed water ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Containers
A container is any receptacle or enclosure for holding a product used in storage, packaging, and transportation, including shipping. Things kept inside of a container are protected on several sides by being inside of its structure. The term is most frequently applied to devices made from materials that are durable and are often partly or completely rigid. A container can also be considered as a basic tool, consisting of any device creating a partially or fully enclosed space that can be used to contain, store, and transport objects or materials. History Humans have used containers for at least 100,000 years, and possibly for millions of years.Clive Gamble, ''Origins and Revolutions: Human Identity in Earliest Prehistory'' (2007), p. 204. The first containers were probably invented for storing food, allowing early humans to preserve more of their food for a longer time, to carry it more easily, and also to protect it from other animals. The development of food storage co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rooftop Water Tower
A rooftop water tower is a variant of a water tower, consisting of a water container placed on the roof of a tall building. This structure supplies water pressure to floors at higher elevation than public water towers. As building height increases, the vertical height of its plumbing also increases. This produces a large water column and the weight of this water produces very high pressure at the bottom of the column. Normally, this would require very thick (heavy-duty) plumbing to survive the pressure. Fittings at the bottom of the column would need pressure reducing valves to operate normally, and municipal water pressure would need to be very high to supply pressure to the top of the column. Instead, the plumbing at various levels of the building are often sequestered, with pressure supplied from a rooftop water tower instead of the municipal supply. The tower itself is fed by a pump and a relatively high pressure line that carries water to the top of the building from the ...

Hypochlorite
In chemistry, hypochlorite, or chloroxide is an oxyanion with the chemical formula ClO−. It combines with a number of cations to form hypochlorite salts. Common examples include sodium hypochlorite (household bleach) and calcium hypochlorite (a component of bleaching powder, swimming pool "chlorine"). The Cl–O distance in ClO− is 1.69 Å. The name can also refer to esters of hypochlorous acid, namely organic compounds with a ClO– group covalently bound to the rest of the molecule. The principal example is ''tert''-butyl hypochlorite, which is a useful chlorinating agent. Most hypochlorite salts are handled as aqueous solutions. Their primary applications are as bleaching, disinfection, and water treatment agents. They are also used in chemistry for chlorination and oxidation reactions. Reactions Acid reaction Acidification of hypochlorites generates hypochlorous acid, which exists in an equilibrium with chlorine. A lowered pH (i.e. towards acid) drives the fo ...

Algaecide
Algaecide or algicide is a biocide used for killing and preventing the growth of algae, often defined in a loose sense that, beyond the biological definition, also includes cyanobacteria ("blue-green algae"). An algaecide may be used for controlled bodies of water ( reservoirs, golf ponds, swimming pools), but may also be used on land for locations such as turfgrass. Types Inorganic compounds Some inorganic compounds are known since antiquity for their algicidal action due to their simplicity. * Copper(II) sulfate remains "the most effective algicidal treatment". A related traditional use is the Bordeaux mixture, used to control fungus on fruits. * Hydrated lime, as a biocide, is allowed in the production of organic foods. Barley straw Barley straw, in England, is placed in mesh bags and floated in fish ponds or water gardens to help reduce algal growth without harming pond plants and animals. Barley straw has not been approved by the United States Environmental Protect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arrange
Arrange is a mythological figure from the Aboriginal Australian creation myth of the Alyawarre people for Karlu Karlu. In the myth, the figure Arrange, who is also referred to as the devil man, comes from Ayleparrarntenhe. Arrange was making a hair belt, which is a traditional adornment worn only by initiated men, while he was on his journey. As he twirled the hair into strings, he dropped clusters of hair on the ground, which turned into the boulders of Karlu Karlu seen today. When he returned, he spat on the ground, creating the granite Granite ( ) is a coarse-grained (phanerite, phaneritic) intrusive rock, intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly coo ... boulders from the central part of Karlu Karlu.

Fiberglass
Fiberglass (American English) or fibreglass (English in the Commonwealth of Nations, Commonwealth English) is a common type of fibre-reinforced plastic, fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic Matrix (composite), matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than Carbon-fiber-reinforced polymers, carbon fiber, it is stronger than many metals by weight, non-magnetic, non-conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins ...

Pounds Per Square Inch
The pound per square inch (abbreviation: psi) or, more accurately, pound-force per square inch (symbol: lbf/in2), is a unit of measurement of pressure or of stress based on avoirdupois units and used primarily in the United States. It is the pressure resulting from a force with magnitude of one pound-force applied to an area of one square inch. In SI units, 1 psi is approximately . The pound per square inch absolute (psia) is used to make it clear that the pressure is relative to a vacuum rather than the ambient atmospheric pressure. Since atmospheric pressure at sea level is around , this will be added to any pressure reading made in air at sea level. The converse is pound per square inch gauge (psig), indicating that the pressure is relative to atmospheric pressure. For example, a bicycle tire pumped up to 65 psig in a local atmospheric pressure at sea level (14.7 psi) will have a pressure of 79.7 psia (14.7 psi + 65 psi). When gauge pressure is referenced to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon Steel
Carbon steel is a steel with carbon content from about 0.05 up to 2.1 percent by weight. The definition of carbon steel from the American Iron and Steel Institute (AISI) states: * no minimum content is specified or required for chromium, cobalt, molybdenum, nickel, niobium, titanium, tungsten, vanadium, zirconium, or any other element to be added to obtain a desired alloying effect; * the specified minimum for copper does not exceed 0.40%; * or the specified maximum for any of the following elements does not exceed: manganese 1.65%; silicon 0.60%; and copper 0.60%. As the carbon content percentage rises, steel has the ability to become harder and stronger through heat treating; however, it becomes less ductile. Regardless of the heat treatment, a higher carbon content reduces weldability. In carbon steels, the higher carbon content lowers the melting point. The term may be used to reference steel that is not stainless steel; in this use carbon steel may include alloy st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rainwater Harvesting Tank, India
Rain is a form of precipitation where water drop (liquid), droplets that have condensation, condensed from Water vapor#In Earth's atmosphere, atmospheric water vapor fall under gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides water for hydroelectricity, hydroelectric power plants, crop irrigation, and suitable conditions for many types of ecosystems. The major cause of rain production is moisture moving along three-dimensional zones of temperature and moisture contrasts known as weather fronts. If enough moisture and upward motion is present, precipitation falls from convection, convective clouds (those with strong upward vertical motion) such as cumulonimbus (thunder clouds) which can organize into narrow rainbands. In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation which forces moist air to condense and ...
