friction drag meaning in Hindi

Examples

1. The sum of friction drag and pressure ( form ) drag is called viscous drag.
2. In such situations, the airfoil is stalled and has higher pressure drag than friction drag.
3. In lighter air, it will cause friction drag.
4. This effect might also be used to reduce skin friction drag on aircraft wings by 40 %.
5. The total of the skin-friction drag and the viscosity-related pressure drag is usually called the profile drag.
6. This suggests that the total parasitic drag observed in turbulent flow is minimally impacted by skin friction drag.
7. Over most of the surface of most airfoils, the boundary layer is naturally turbulent, which increases skin-friction drag.
8. The air's viscosity resists the shearing, giving rise to a shear stress at the airfoil's surface called skin-friction drag.
9. Wave drag is one of the forms of drag created by swimmers, the others being pressure drag and friction drag.
10. The friction drag force, which is a tangential force on the aircraft surface, depends substantially on boundary layer configuration and viscosity.
