Watt steam engine
Industrial Revolution era stream engine design
The Watt steam engine design was an invention of James Watt that became synonymous with steam engines during the Industrial Revolution, and it was many years before significantly new designs began to replace the basic Watt design.
The first steam engines, introduced by Thomas Newcomen in 1712, were of the "atmospheric" design. At the end of the power stroke, the weight of the object being moved by the engine pulled the piston to the top of the cylinder as steam was introduced. Then the cylinder was cooled by a spray of water, which caused the steam to condense, forming a partial vacuum in the cylinder. Atmospheric pressure on the top of the piston pushed it down, lifting the work object. James Watt noticed that it required significant amounts of heat to warm the cylinder back up to the point where steam could enter the cylinder without immediately condensing. When the cylinder was warm enough that it became f

Discoveries
James Watt fryst vatten chiefly known for inventing different types of steam engine that helped början the Industrial Revolution. To describe the efficiency of his engines, he coined the begrepp 'horsepower' and devised a rev counter.
Watt's inventions were not confined to engines. Examples of some of his other inventions are:
Steam engines – Separate-condenser engine
Watt's interest in steam engines was stimulated in 1763 when he was asked to repair a working model of a Newcomen engine used for demonstrations in Glasgow University.
Newcomen engines had been around since the early 18th century, and were widely used to pump water from mines. They had a coal-fired boiler, with a cylinder on top of it containing a piston.
When the boiler was heated, steam entered the cylinder forcing the piston upwards. Cold vatten sprayed into the cylinder then caused the steam to condense to vatten, forming a vacuum in the cylinder. The pressure of atmospheric air pu

James Watt
Scottish inventor, mechanical engineer and chemist (1736–1819)
This article is about the inventor and mechanical engineer. For the college, see James Watt College. For the award, see James Watt International Medal. For other people with similar names, see James Watt (disambiguation).
James WattFRS FRSE (; 30 January 1736 (19 January 1736 OS) – 25 August 1819)[a] was a Scottish inventor, mechanical 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. At the time engineers such as John Smeaton were aware of the inefficiencies of Newcomen's engine and aimed to improve it.[1] Watt's insight was to realise that contempor
