Megawatt
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circu ...

Wind Farm
A wind farm or wind park, also called a wind power station or wind power plant, is a group of wind turbines in the same location used to produce electricity. Wind farms vary in size from a small number of turbines to several hundred wind turbines covering an extensive area. Wind farms can be either onshore or offshore. Many of the largest operational onshore wind farms are located in China, India, and the United States. For example, the largest wind farm in the world, Gansu Wind Farm in China had a capacity of over 6,000 MW by 2012,Watts, Jonathan & Huang, CecilyWinds Of Change Blow Through China As Spending On Renewable Energy Soars ''The Guardian'', 19 March 2012, revised on 20 March 2012.

Jaffna Lagoon
Jaffna Lagoon is a large lagoon off Jaffna District and Kilinochchi District, northern Sri Lanka. The lagoon is surrounded by the densely populated Jaffna Peninsula containing palmyra palms, coconut plantations, and rice paddies. There are numerous fishing villages and some salt pans. The lagoon has extensive mudflats, seagrass beds and some mangroves. The lagoon attracts a wide variety of water birds including American flamingoes, ducks, gulls, terns and other shorebirds. Jaffna Lagoon Jaffna Lagoon is a shallow coastal stretch of water between the Jaffna and the Kilinochchi Districts in northern Sri Lanka. It is located between the longitudes of 79°54E and 80°20E, and the latitudes of 9°30N and 9°50N, and connected to Palk Bay through a channel to the west. It is connected to two internal lagoons, Vadamarachchi Lagoon and Uppu Aru Lagoon, and the external Chundikkulam Lagoon (sometimes known as Elephants Pass Lagoon).

Northern Province, Sri Lanka
The Northern Province ( ta, வட மாகாணம் ''Vaṭa Mākāṇam''; si, උතුරු පළාත ''Uturu Paḷāta'') is one of the nine provinces of Sri Lanka, the first level administrative division of the country. The provinces have existed since the 19th century but did not have any legal status until 1987 when the 13th Amendment to the Constitution of Sri Lanka established provincial councils. Between 1988 and 2006 the province was temporarily merged with the Eastern Province to form the North Eastern Province. The capital of the province is Jaffna. The majority of the Sri Lankan Civil War occurred in this province. History Parts of present-day Northern Province were part of the pre-colonial Jaffna kingdom. Other parts were ruled by Vanniar Chieftains who paid tribute to the Jaffna kingdom. The province then came under Portuguese, Dutch and British control. In 1815 the British gained control of the entire island of Ceylon. They divided the island ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Sunday Times (Sri Lanka)
''The Sunday Times'' is a weekly Sri Lankan broadsheet initially published by the now defunct Times Group, until 1991, when it was taken over by Wijeya Newspapers.

Revolutions Per Minute
Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or with the notation min−1) is a unit of rotational speed or rotational frequency for rotating machines. Standards ISO 80000-3:2019 defines a unit of rotation as the dimensionless unit equal to 1, which it refers to as a revolution, but does not define the revolution as a unit. It defines a unit of rotational frequency equal to s−1. The superseded standard ISO 80000-3:2006 did however state with reference to the unit name 'one', symbol '1', that "The special name revolution, symbol r, for this unit is widely used in specifications on rotating machines." The International System of Units (SI) does not recognize rpm as a unit, and defines the unit of frequency, Hz, as equal to s−1. :\begin 1~&\text &&=& 60~&\text \\ \frac~&\text &&=& 1~&\text \end A corresponding but distinct quantity for describing rotation is angular velocity, for which the SI unit is the ...

Electricity In Sri Lanka
The electricity sector in Sri Lanka has a national grid which is primarily powered by hydroelectric power and thermal power, with sources such as photovoltaics and wind power in early stages of deployment. Although potential sites are being identified, other power sources such as geothermal, nuclear, solar thermal and wave power are not used in the power generation process for the national grid. The country is expected to achieve 75% electricity generation by renewable energy by 2025. History Sri Lanka (then Ceylon) first witnessed electricity in 1882 when SS Helios docked in Colombo for a local electricity exhibition. In 1890, using a diesel generator the first electric bulb in Ceylon was lit with electricity in the Billiard Room of Bristol Hotel in Colombo, before electric lights became an established commercial product. In 1895, Messrs Boustead Bros established a small power station in Bristol Building, Fort. The power station was the first commercial power stati ...
