Turgo turbine and generator At Milford Sound, New Zealand. The Turgo turbine is an impulse water turbine designed for medium head applications. Operational Turgo turbines achieve efficiencies of about 87%. In factory and lab tests Turgo turbines perform with efficiencies of up to 90%. It works with net heads between 15 and 300 m. [1]
The company makes hydropower turbines and engine cooling pumps. One of the company's notable products is the Turgo turbine, invented in 1919 by Eric Crewdson whose grandson Charles Crewdson OBE is, as of 2021 the company chairman. [3]
The impulse energy of the water jet exerts torque on the bucket-and-wheel system, spinning the wheel; the water jet does a "u-turn" and exits at the outer sides of the bucket, decelerated to a low velocity. In the process, the water jet's momentum is transferred to the wheel and hence to a turbine. Thus, "impulse" energy does work on the turbine.
An impulse turbine is one in which the pressure of the fluid flowing over the rotor blades is constant and all the work output is due to the change in kinetic energy of the fluid. Prior to hitting the turbine blades, the water's pressure ( potential energy ) is converted to kinetic energy by a nozzle and focused on the turbine.
A steam turbine with the case opened Humming of a small pneumatic turbine used in a German 1940s-vintage safety lamp. A turbine (/ ˈ t ɜːr b aɪ n / or / ˈ t ɜːr b ɪ n /) (from the Greek τύρβη, tyrbē, or Latin turbo, meaning vortex) [1] [2] is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work.
Later designs such as the Turgo turbine, first patented in 1919, and the Banki turbine were inspired by the Pelton wheel. [citation needed] In 1895, The Franklin Institute in Philadelphia, Pennsylvania, awarded Lester Pelton the Elliott Cresson Medal, since renamed the Benjamin Franklin Medal, for Pelton's accomplishments of invention in ...
A major new study has revealed a long list of benefits and some little-known risks of Ozempic and other GLP-1 medications. Experts break down the findings.
The first impulse type turbine was created by Carl Gustaf de Laval in 1883. This was closely followed by the first practical reaction type turbine in 1884, built by Charles Parsons . Parsons’ first design was a multi-stage axial-flow unit, which George Westinghouse acquired and began manufacturing in 1895, while General Electric acquired de ...
