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 40 M/SEC 22.5 M/SEC 33 M/SEC 50 M/SEC 40 M/SEC 22.5 M/SEC 33 M/SEC 50 M/SEC ANSWER DOWNLOAD EXAMIANS APP
Hydraulics & Fluid Mechanics Two dimensional flow occurs when the fluid particles move in plane or parallel planes and the streamline pat-terns are identical in each plane 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 magnitude and direction of the velocity do not change from point to point in the fluid the fluid particles move in plane or parallel planes and the streamline pat-terns are identical in each plane 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 magnitude and direction of the velocity do not change from point to point in the fluid ANSWER DOWNLOAD EXAMIANS APP
