blimp typically flies at 20 m/s in air at standard conditions. In order to model the blimp’s behavior in a wind tunnel, a 1:20 scale model is created and tested at the same air temperature in order to determine the drag. (a) What is the appropriate dimensionless parameter to use so that dynamic similarity is maintained? (b) At a model velocity of 75 m/s, what is the appropriate air pressure in the wind tunnel? (c) If a drag force of 214 N is measured on the model, what would the corresponding drag on the prototype be?
