A turbine (/ ˈ t ɜːr b aɪ n / or / ˈ t ɜːr b ɪ n /) (from the Latin turbo, a vortex, related to the Greek τύρβη, tyrbē, meaning "turbulence") is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work.The work produced by a turbine can be used for generating electrical power when combined with a generator. x���KO1 ��J�渋��3��qj��*Zȶ������[���x/{����Omc���ϓ��-Ct���y�6WG�k���J`��6۱�� ��D�����Q�\�͓��&�@`&������͘]��z� ���a$��1����m�;�o`��6���j�����Q�(|���[�W0|��gܝ��/�Ҏ �����YBI�0Γ��{���ea�SDO�����*�HHbL�,�jYNR#mupL�c,M�idNl-�XL�0 endstream

TURBINES IN ACTION Broadly speaking, we divide turbines into four kinds according to the type of fluid that drives them: water, wind, steam, and gas. Only in the section Reaction Turbine Principle: In the case of reaction turbine, the moving blades of a turbine are shaped in such a way that the steam expands and drops in pressure as it passes through them. <>
