WattThe 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⋅m⋅s. It is used to quantify the rate of energy transfer. The watt is named in honor of James Watt (1736–1819), an 18th-century Scottishinventor, mechanical engineer, and chemist who in 1776 improved the Newcomen engine with his own steam engine, which became fundamental for the Industrial Revolution.
James WattJames Watt (; 30 January 1736 (19 January 1736 OS) – 25 August 1819) was a Scottish inventor, engineer and chemist who improved on Thomas Newcomen's 1712 Newcomen steam engine with his Watt steam engine in 1776, which was fundamental to the changes brought by the Industrial Revolution in both his native Great Britain and the rest of the world. While working as an instrument maker at the University of Glasgow, Watt became interested in the technology of steam engines.Power (physics)Power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt (symbol W), equal to one joule per second (J/s). Power is a scalar quantity. The output power of a motor is the product of the torque that the motor generates and the angular velocity of its output shaft.
TurbineA turbine ( or ) (from the Greek τύρβη, tyrbē, or Latinturbo, meaning vortex) is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. The work produced can be used for generating electrical power when combined with a generator. A turbine is a turbomachine with at least one moving part called a rotor assembly, which is a shaft or drum with blades attached.
Electric motorMachine that converts electrical energy into mechanical energyAn electric motor is a machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate Lorentz force in the form of torque applied on the motor's shaft.
Draft horseA draft horse (US) or draught horse (UK), also known as dray horse, carthorse, work horse, or heavy horse, is a large horse bred to pull heavy loads and work agricultural tasks such as plowing. A number of breeds with varying characteristics are of this type, but all share common traits of strength, patience, and a docile temperament.
Unit of measurementA unit of measurement, or unit of measure, is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity. Any other quantity of that kind can be expressed as a multiple of the unit of measurement, For example, a length is a physical quantity. The metre (symbol: m) is a unit of length that represents a definite predetermined length.
International System of UnitsThe International System of Units, internationally known by the abbreviation SI (from its official French name, Système international d'unités), is the modern form of the metric system and the world's most widely used system of measurement. It is the only system of measurement with official status in nearly every country in the world, employed in science, technology, industry, and everyday commerce.
Work (physics)In science, work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form, for a constant force aligned with the direction of motion, the work equals the product of the force strength and the distance traveled. A force is said to do positive work if it has a component in the direction of the displacement of the point of application.
Scottish peopleEthnic group native to ScotlandEthnic groupScottish people or Scots (Scots: Scots fowk; Scottish Gaelic: Albannaich) are an ethnic group and nation native to Scotland. Historically, they emerged in the early Middle Ages from an amalgamation of two Celtic peoples, the Picts and Gaels, who founded the Kingdom of Scotland (or Alba) in the 9th century.Reciprocating engineA reciprocating engine, more often known as a piston engine, is a heat engine that uses one or more reciprocatingpistons to convert high temperature and high pressure into a rotating motion. This article describes the common features of all types. The main types are: the internal combustion engine, used extensively in motor vehicles; the steam engine, the mainstay of the Industrial Revolution; and the Stirling engine for niche applications.*As an Amazon Associate I earn from qualifying purchases.
