Drag is the force component exerted on an immersed object, ?
Correct answer: B. The component being parallel to the flow direction
- A. Passing the centroid of the body at 60°to the direction of motion
- B. The component being parallel to the flow direction
- C. The component being normal to the flow direction
- D. None of these
Explanation
Drag is the component of fluid force parallel to the relative flow or motion direction. The normal component is called lift.
