| 1. | They are available in broad range of sizes, capacities and speed ratios.
|
| 2. | It is the inverse of the tip speed ratio used for wind turbines.
|
| 3. | The machine showed the speed ratio has been consistent from 1998-2000.
|
| 4. | Thus, the speed ratio of a gear train also defines its mechanical advantage.
|
| 5. | The speed ratio of a machine can be calculated from its physical dimensions.
|
| 6. | The blade-to-gas speed ratio parameter ( velocity ratio ) ? = u / c 2.
|
| 7. | By extension, the efficiency of the wind turbine is a function of the tip-speed ratio.
|
| 8. | "' Variation of stage efficiency of an IFR turbine with blade-to-isentropic gas speed ratio "'
|
| 9. | It is generally assumed to be a function of both tip-speed ratio and pitch angle.
|
| 10. | A single action rotates both surfaces at a fixed speed ratio determined by the gear.
