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

50 M/SEC
22.5 M/SEC
40 M/SEC
33 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 direction and magnitude of the velocity at all points are identical
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
