A wind tunnel is being used to study the aerodynamics of a full-scale model rocket that is 30 cm long. Scaling for drag calculations are based on the Reynolds number. The rocket has an expected maximum velocity of 190 km/h. What is the Reynolds number at this speed? Assume ambient air is at 20°C. The wind tunnel is capable of speeds up to 160 km/h; so an attempt is made to improve this top speed by varying the air temperature. Calculate the equivalent speed for the wind tunnel using air at 5°C and 65°C. Would replacing air with carbon dioxide provide higher equivalent speeds?

Question
A wind tunnel is being used to study the aerodynamics of a full-scale model rocket that is 30
cm long. Scaling for drag calculations are based on the Reynolds number. The rocket has
an expected maximum velocity of 190 km/h. What is the Reynolds number at this speed? Assume
ambient air is at 20°C. The wind tunnel is capable of speeds up to 160 km/h; so an attempt is
made to improve this top speed by varying the air temperature. Calculate the equivalent speed
for the wind tunnel using air at 5°C and 65°C. Would replacing air with carbon dioxide provide
higher equivalent speeds?
