What are the parameters that affect life and drag forces on an aerofoil?
Vinil7 [7]

Answer:

1.The velocity of fluid

2.Fluid properties.

3.Projected area of object(geometry of the object).

Explanation:

Drag force:

 Drag force is a frictional force which offered by fluid when a object is moving in it.Drag force try to oppose the motion of object when object is moving in a medium.

Drag force given as

F_D=\dfrac{1}{2}\rho\ A\ V^2

So we can say that drag force depends on following properties

1.The velocity of fluid

2.Fluid properties.

3.Projected area of object(geometry of the object).

Please help me with this question
Lera25 [3.4K]

Answer:

  4.2

Explanation:
