The wind tunnel is designed so that the lower pressure outside the testing region B draws air out in order to reduce the boundary layer. Within region B there are 1000 holes, each 4 mm in diameter. If the pressure is adjusted so that the average velocity of the air through each hole is 10 m/s, determine the average velocity of the air exiting the tunnel at C. (Assume the air is incompressible).
