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