Learn about the history, working principle, types and applications of centrifugal pumps, which are used to transport fluids by converting rotational energy to hydrodynamic energy. Find out how Euler's pump equation, velocity triangle and efficiency factor describe the performance of centrifugal pumps.
Appold was the son of a fur-skin dyer, established in Finsbury. Succeeding to his father's business at the age of twenty-two, he introduced into it so many scientific improvements that he soon amassed a considerable fortune and was able to devote his time and attention to his favourite mechanical pursuits.
A centrifugal governor is a device that controls the speed of an engine by regulating the flow of fuel or working fluid. Learn about its invention by James Watt, its use on steam engines and other machines, and its role in dynamic systems and natural selection.
The son of the clothier Carl Pfleiderer (1845–1927) and his wife Marie (née Wirth; 1847–1895), Pfleiderer graduated in 1899 from the secondary school.He studied from 1901 to 1905 mechanical engineering at the Technical University of Stuttgart and completed his studies with the state examination and the degree of Diplôme d'ingénieur.
An impeller, or impellor, is a rotating device that increases the pressure and flow of a fluid. Learn about different types of impellers, such as open, closed, screw, and water jet impellers, and their uses in pumps, compressors, water jets, tanks, and medicine.
Plate Forced Circulation Evaporators utilize a centrifugal pump which forces liquid to circulate through the plate structures and heat exchanger. [12] The flexibility of this design is a major advantage, as the rate of evaporation can be manipulated by either adding or removing extra plates, allowing it to perform a wide range of duties that ...
Gwynnes Limited was a City of London England engineering business, iron founders and pump makers founded in 1849 to capitalise on the centrifugal pump invented [note 1] by James Gwynne (1804–1850). [ note 2 ] In 1856 his eldest son, James Eglinton Anderson Gwynne (1832–1915), of Essex Street Wharves on the south side of The Strand was ...
In the pump, the radial or static pressure, due to centrifugal force, is added to the tangential or dynamic, thus increasing the effective head and assisting in the expulsion of the fluid. In the motor, on the contrary, the first named pressure, being opposed to that of supply, reduces the effective head and the velocity of radial flow toward ...
