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 22.5 M/SEC 33 M/SEC 40 M/SEC 50 M/SEC 22.5 M/SEC 33 M/SEC 40 M/SEC 50 M/SEC ANSWER DOWNLOAD EXAMIANS APP

Hydraulics & Fluid Mechanics Non uniform flow occurs when velocity, depth, pressure, etc. change from point to point in the fluid flow the direction and magnitude of the velocity at all points are identical 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 velocity, depth, pressure, etc. change from point to point in the fluid flow the direction and magnitude of the velocity at all points are identical 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 ANSWER DOWNLOAD EXAMIANS APP
