The aerodynamic drag of a prototype car is to be predicted at a speed of 25 m/s at 25⁰C. Automotive engeneers buid a one-fith-scale Modul car to first in a wind tunnel under the same environmental conditions. The densty and viscosity of air at 25⁰C are 1.1 kg m³ and 2×10⁻⁵kg/m−5. respectively. If the dimension of the modeel car is 1 m. find the velocity of the model car.
