| 1. | Traveling in such a bubble held the potential to reduce the frictional drag radically.
|
| 2. | This induced drag is a pressure drag which has nothing to do with frictional drag.
|
| 3. | There is a frictional drag that is given by the shear due to the viscosity.
|
| 4. | Where f _ r is the frictional drag coefficient.
|
| 5. | Wind speed increases with height and is lower towards the ground due to frictional drag.
|
| 6. | The frictional drag of water against the metal skin of the projectile rapidly saps its energy.
|
| 7. | Wind waves also act to modify atmospheric properties through frictional drag of near-surface winds and heat fluxes.
|
| 8. | The increase causes the Earth's atmosphere to balloon to new heights, creating new frictional drag on orbiting satellites.
|
| 9. | Swimming organisms with a fusiform shape are likely to experience the greatest reduction in both pressure and frictional drag.
|
| 10. | The frictional drag of the blooming atmosphere is causing the orbital outpost to descend between one and two miles each week.
