A group of engineers is planning to built a tunnel going through a mountain range for vehicle to pass through. Assume the built tunnel has a diameter of 15m, wind (air) at 20 °C and 20m/s is flowing across the tunnel with p = 1.204 kg/m³ and µ = 1.825 x 10-5kg/ms. The width of the approaching vehicle is given to be 2.5m. Implementing the dimensionless parameters obtain in (a), determine the speed of air and the width of body if the experimental work is to be run in a wind tunnel with a diameter of 5m at 25 °C (p = 1.184 kg/m³ and u = 1.849 x 10-5kg/ms.)
