In case of impulse steam turbine mcq
WebA steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first … Web1) Steam turbine: In a steam turbine, the working fluid is steam. The pressure of steam is converted into the mechanical work of the shaft. This turbine is classified as: A) Impulse turbine:- In an impulse turbine the total pressure energy of the fluid is completely converted into kinetic energy before it strikes rotor blades.
