499)A small round object is tested in a 0.75 m diameter ind tunnel. The pressure is uniform across sections ? and ? The upstream pressure is 30 mm H2O (gage), the downstream pressure is 15 mm H20 (gage), and the mean air speed is 12.5 m/s. The velocity profile at section ? is linear it varies from zero at the tunnel centerline to a maximum at the tunnel wall. Calculate (a) the mass flow rate in the wind tunnel, (b) the maximum velocity at section ?, and (c) the drag of the object and its supporting vane. Neglect viscous resistance at the tunnel wall. max V, 2
