Example 12.4 Given: A 1/20 scale model of a high-rise building is tested in a wind tunnel. The drag force of the model on the rectangular face is measured to be 200 N for a wind speed of 20 m/s. Find: The drag force on the prototype building in a 40 m/s wind velocity using the drag coefficient conservation. Note: prototype height=3w. Tair = constant Match force coefficients.
