Question 3 (20 pts, 15 min): Wind is blowing at 2 m/s as the truck moves forward into the wind at 8 m/s. If the air has a temperature of 20°C, the fluid properties are p = 1.202 kg/m3 and V = 15.1 (10) m/s. a) Justify and explain which group of equations is appropriate to use for the boundary layer created on top of the truck (Laminar, turbulent, or both). b) What is the total frictional drag force (FS) on top of the truck (BEFC)? Assume boundary layer is completely turbulent. c) Calculate the drag coefficient for the truck. 8 m/s 8 m E 7 4m 2 m/s
