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

a)    22.5 m/sec.
b)    33 m/sec.
c)    40 m/sec.
d)    90 m/sec.

Ans: c
