Wind can produce very high drag loads on high-rise bulidings. Since calculating the áow around a building is quite diffcult, you decide to perform an experiment to find the drag on the nearly completed Mirabella building at Univesity Drive and Myrtle Avenue in Tempe. The building is 250 ft tall and approximately 210 ft wide (at its widest part) A) determine the drag on the Mirabella building for a sustained wind speed of 40 mph. Suppose that the temperature remains the same both inside and outside of the wind tunnel test section. If the atmospheric pressure is 100 kPa, what would the pressure have to be inside the tunnel test section to maintain dynamic similarity between the model and the full-scale building? (You may assume that the tunnel is operating at maximum speed.
