A 0.5 scale model car is to be tested in a wind tunnel. The conditions of the actual car are V = 70 km/h and T = 0 C and the air temperature in the wind tunnel is 20 C. To achie imilarity, the wind tunnel velocity (in km/h) should be ? Air at 1 atm and 0 C: 1.292 kg/m^3, 1.338x10^(-5) m^2/s; Air at 1 atm and 20 C: 1.204 kg/m^3, 1.516x10^(-5) m^2/s" 237.9
