Calculate the lift and drag, and the power necessary to drive the airfoil at this speed through air of (a) 101.3 kPa and 15°C, and (b) 79.3 kPa and −18°C. CD = 0.035; CL = 0.46.

Is there any conflict between the boundary condition respect to the airfoil surface and the induced velocity on the lifting line? Why?
Air is flowing past a symmetrical airfoil at an angle of attack of 5°. Is the (a) lift and (b) drag acting on the airfoil zero or nonzero?
The rectangular wings of a microlight aircraft have a combined spanwise length of
9.144 m and streamwise (direction of air flow) width of 0.9144 m The wings have a
coefficient of form drag of 0.01 and a lift coefficient of 0.3 in cruise.
When cruising at a speed of 150km/h and altitude of 3,000 feet, the temperature and
absolute pressure of the atmospheric air are 5°C and 90 kPa, respectively.
