Q. In a two dimensional incompressible steady flow around an airfoil, the stream lines are 2 cm apart at a great distance from the airfoil, where the velocity is 30 m/sec. The velocity near the airfoil, where the stream lines are 1.5 cm apart, is (Solved)
1. 22.5 m/sec.
2. 33 m/sec.
3. 40 m/se
4. 90 m/sec.
- c. 40 m/sec.
