The drag characteristics of an aircraft must be determined by a test of a model subjected to a wind tunnel operated at an absolute pressure of 1300 KPa. If the prototype will be used in standard air at 385 km/hr, and the corresponding speed of the model does not differ by more than 20% from the speed of the prototype (so that the compressibility effects are ignored), what range of length scales can be used if the Reynolds number remains similar? Assume that the viscosity of the air is not affected by the pressure, and that the air temperature in the wind tunnel is equal to the air temperature to which the prototype will be subjected.
