Robert D. Napier
Robert D. Napier (1821 – May 1885) was a Scottish engineer, and the youngest son of David Napier (marine engineer). Educated in Liverpool and London, Robert D. Napier worked, with brothers John D. and Francis ("Frank") for his father's shipbuilding firm. At the age of 30, he moved to Australia, where he oversaw dredging operations in Sydney Harbour. While there, he invented the "Differential Self-Acting Friction Brake" and the "Napier Windlass". In 1856 he brought out to Port Adelaide, South Australia in sections, a paddle-steamer ''Moolgewanke'' for trading on the River Murray. He and partner Capt. William Webb operated her for a few years from Goolwa before selling her, with barge ''Unknown'', to George Bain Johnston. He was also involved with Capt. William McCoy in operating the paddle steamer ''Leichardt''. He returned to Scotland about 1865–1866 and established a new business "Napier Brothers" with his brother John. Napier also experimented and wrote on a number of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

De Laval Nozzle
A de Laval nozzle (or convergent-divergent nozzle, CD nozzle or con-di nozzle) is a tube which is pinched in the middle, with a rapid convergence and gradual divergence. It is used to accelerate a compressible fluid to supersonic speeds in the axial (thrust) direction, by converting the thermal energy of the flow into kinetic energy. De Laval nozzles are widely used in some types of steam turbines and rocket engine nozzles. It also sees use in supersonic jet engines. Similar flow properties have been applied to jet streams within astrophysics. History Giovanni Battista Venturi designed converging-diverging tubes known as Venturi tubes for experiments on fluid pressure reduction effects when fluid flows through chokes ( Venturi effect). German engineer and inventor Ernst Körting supposedly switched to a converging-diverging nozzle in his steam jet pumps by 1878 after using convergent nozzles but these nozzles remained a company secret. Later, Swedish engineer Gustaf de Lav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Engineers From Glasgow
Engineers, as practitioners of engineering, are professionals who invent, design, build, maintain and test machines, complex systems, structures, gadgets and materials. They aim to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin , the origin of the Ir. in the title of engineer in countries like Belgium, The Netherlands, and Indonesia) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of a licensed professional engineer typically include a four-year bachelor's degree in an engineering dis ...
