Include 00 1) If c is the chord of an airfoil, U is the free stream velocity, p is the free stream pressure, ? is the free stream density , ν is the kinematic viscosity and ζ is the vorticity, which of the following quantities is NOT nondimensional a. U /sqrt(p/ ?) b. U ζ/c c. cζ/U d. c ^2 ζ/ ν e. U*c/ ν 2) For what values of the constant s “a” and “b” do the velocity components u= x^2 + a y^2 ; v=b x y + 4 represent an incompressible and irrotational flow: a. (a,b)=(-1, -2) b. (a,b)=(1, 2) c. (a,b)=(-2, -1) d. (a,b)=(2, 1) e. (a,b)=(2, -1) 3) The velocity potential of a uniform stream with speed 3m/s and a 2D source with strength 2 m^2/s is a. 3 x + 2 ln(r) b. -2 y + 3 ln(r) c. 3 x + ln(r)/ π d. 3 y + 2 θ e. 3 y – 2 θ / π 4) Consider a 2D flow in the first quadrant, x>0, y>0.
