Consider a symmetrical cylindrical body immersed in a fluid flow. The flow around the body is steady and laminar, and the cylinder is non-rotating. Which of the following statements best describes the nature of drag and lift forces acting on the cylinder?

Share:
- 1The drag force is negligible compared to the lift force due to the body’s shape and orientation.
- 2The drag force is a combination of pressure and friction drag, while the lift force is zero for a symmetrical non-rotating body in steady laminar flow.✓
- 3The drag force is primarily due to pressure drag, and the lift force can exist due to vortex shedding.
- 4The drag force is primarily due to friction drag, and the lift force is zero due to the symmetrical shape
Correct answer
The drag force is a combination of pressure and friction drag, while the lift force is zero for a symmetrical non-rotating body in steady laminar flow.
