An airship is o operate at 20 m/s in air at staanclard conditions. a model is constructed to2scale and tested in a wind tunnel at the same air temperature to determine drag. what criterion should be considered to obtain dynamic similarity? lf the moel is sicd at ts n/s, what pres should be used in the wind tunnel? if the model drag force is 250 n, what will be the drag of the prototype?
