Question 1 20 A Peugeot 208 T16 is tackling Pikes Peak and doing 320 km/h through still air (p = 1.225 kg/m). At a point on the rear aerofoil (wing) the air speed relative to the aerofoil is 435 km/h. Ignoring viscous effects: 1. a) What suction (i.e. negative gauge) pressure develops on the aerofoil at that point? [14] 2. b) What is the pressure at the aerofoil's leading edge (a stagnation point)? [6] Upload Choose a File Question 2 20 pts The disgraced former Attorney General Fal Rawee relocates to a remote shack where the average wind speed is 65 km/h. It accelerates as it flows up and over the roof. The free-stream pressure blowing towards the AG's abode, as well as the pressure inside, is one atmosphere. You may take the air density as 1.225 kg/m and ignore elevation and viso ects. (a) Calculate the pressure difference between inside and outside at the point on the roof where the wind-speed is 100 km/h. Would this effect tend to push the shack down or lift it? (121 (b) Determine the pressure difference on a wall facing the wind. Take it as a stagnation point. [8] Upload Choose a File Question 3 20 pts w
