pressure drag meaning in Hindi

Examples

1. Pressure drag is the strongest component of drag here, am I right?
2. The pressure drag created allows for the upward lift of the fish.
3. The low-pressure drag on the leader is diminished by the second car.
4. Wave drag presents itself as part of pressure drag due to compressibility effects.
5. This induced drag is a pressure drag which has nothing to do with frictional drag.
6. In such situations, the airfoil is stalled and has higher pressure drag than friction drag.
7. The total of the skin-friction drag and the viscosity-related pressure drag is usually called the profile drag.
8. For aircraft and rockets, below Mach . 8, the nose pressure drag is essentially zero for all shapes.
9. This represents an optimum compromise between the pressure drag from flow separation and skin friction from induced turbulence.
10. Some flat-shaped fish can take advantage of pressure drag by having a flat bottom surface and curved top surface.
