A general aviation aircraft has a wing span b = 18 meters and an aspect ratio AR = 8. In a given equilibrium flight condition, at an equivalent airspeed V_eq = 60 m/s, the lift and drag force are L = 24 kN and D = 4 kN, respectively. Find the lift coefficient C_L and the drag coefficient C_D. A gust momentarily increases the angle of attack by 0.5 degree, without changing the equivalent airspeed, resulting in an additional 4 kN of lift. Find the slope of the lift coefficient curve C_L alpha, expressed per degree.
A centrifugal pump is used to raise water against a static head of 18.0 m. The suction and delivery pipes, both 0.15 m diameter, have, respectively, friction head losses amounting to 2.25 and 7.5 times the dynamic head.
