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.
