WebHydro turbines are devices used in hydroelectric generation plants that transfer the energy from moving water to a rotating shaft to generate electricity.These turbines rotate or spin as a response to water being … Web31 mrt. 2003 · A pure jet is thus VERY inefficient at low forward speeds, and improves at very high speeds. RPM of a big fan, Mmm. A 12 ft dia. fan, about 2000 rpm? Correct me if I'm a long way out! The Comet 1's DH Ghost centrifugal gas turbines turned at about 5,500 rpm from memory - quite a big chunk of rotating mass there.
