Required information In wind tunnels the test section is perforated to suck

Required information In wind tunnels the test section is perforated to suck out fluid and provide a thin viscous boundary layer. The test section wall contains 1200 holes of 5-mm diameter each per square meter of wall area. In the figure, Dr 24 m. D, 0.85 m. Do= 26 m. The suction velocity through each hole is Vs 8 m/s, and the test-section entrance velocity is V = 35 m/s. Assume incompressible steady flow of air at 20C Determine the value of Vo Test section D, Uniform suction Do Vo L-4m
