Some articles on blades, blade efficiency:
... In the reaction turbine, the rotor blades themselves are arranged to form convergent nozzles ... The steam then changes direction and increases its speed relative to the speed of the blades ... Blade efficiency Energy input to the blades in a stage is equal to the kinetic energy supplied to the fixed blades (f) + the kinetic energy supplied to the moving blades (m) ...
... which is converted into shaft rotation by the bucket-like shaped rotor blades, as the steam jet changes direction ... A pressure drop occurs across only the stationary blades, with a net increase in steam velocity across the stage ... The steam leaving the moving blades has a large portion of the maximum velocity of the steam when leaving the nozzle ...
Famous quotes containing the words efficiency and/or blade:
“Nothing comes to pass in nature, which can be set down to a flaw therein; for nature is always the same and everywhere one and the same in her efficiency and power of action; that is, natures laws and ordinances whereby all things come to pass and change from one form to another, are everywhere and always; so that there should be one and the same method of understanding the nature of all things whatsoever, namely, through natures universal laws and rules.”
“I would not knock old fellows in the dust
But there lay Captain Carpenter on his back
His weapons were the old heart in his bust
And a blade shook between rotten teeth alack.”
—John Crowe Ransom (18881974)
