Hydraulics & Fluid Mechanics
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

33 M/SEC
50 M/SEC
22.5 M/SEC
40 M/SEC

Hydraulics & Fluid Mechanics
Steady flow occurs when

the velocity of successive fluid par-ticles, at any point, is the same at suc-cessive periods of time
the fluid particles move in plane or parallel planes and the streamline pat-terns are identical in each plane
the magnitude and direction of the velocity do not change from point to point in the fluid
the direction and magnitude of the velocity at all points are identical
