11. Once the desired specific speed is known, basic dimensions of the unit's components can be easily calculated. 12. The factor 0.2626 is only required when the specific speed is to be adjusted to English units. 13. The specific speed is the main criterion for matching a specific hydro-electric site with the optimal turbine type. 14. In countries which use the metric system, the factor is omitted, and quoted specific speeds are correspondingly larger. 15. The 5 Gbit / s rate was added to accommodate so implementation specific speeds supported by certain FPGAs. 16. On the other hand, Francis turbine works on low Specific speeds i . e ., high pressure heads. 17. In a vacuum, Maxwell's equations predict that these disturbances will travel at a specific speed , denoted by the symbol. 18. Like the processor in a PC, a video card also has a chip that runs at a specific speed . 19. However, the larger the augmenter duct, the more drag it produces, and it is only effective within specific speed ranges. 20. At a particular instant the rock is a specific distance from the surface of the earth traveling at a specific speed .
