Across
- 6. no edge spillage drag
- 8. different car body types
- 9. body result in less flow separation
- 13. principal of aerodynamics
- 14. vehicle body construction
- 15. great resistance to wind
Down
- 1. tend to decrease fluid velocity to solid
- 2. force acting normal to object surface
- 3. offered by the air to the movement of body
- 4. friction independent of turbulent
- 5. force acting tangential to object surface
- 7. friction between the fluid and a surface
- 10. due to size and shape of a body
- 11. drag apears with wings or lifting body
- 12. drag is dominated by viscus force
