Question 1 Which statement is correct? For an infinitely thin flat plate

Question 1 Which statement is correct? For an infinitely thin flat plate parallel to the flow the drag coefficient is relatively low compared to when the plates are normal to the flow. This occurs since: 1) Pressure (form) drag only has a small area to act on 2) Skin friction drag only has a small area to act on 3) None of the listed statements are correct 4) Pressure (form) drag is zero and skin friction drag is relatively low 5) Pressure (form) and skin friction drags are in balance Question 2 Which statement is true? For an aircraft wing, induced drag is proportional to: 1) Coefficient of lift and minimized by a simple tapered platform 2) None of the listed statements are correct 3) Coefficient of lift and is minimized by an ellipsoidal wing platform
