A wing is designed to operate with free stream velocity of 20m/s and air density of 1.225 kg/m3. Find aerodynamic efficiency of given wing. Consider S as 8 m2, CL as 0.9 and CD as 1.25.

Aerodynamics topics include: Aerodynamic forces and coefficients, aerodynamics lift, parasite drag and drag due to lift. Aerodynamics is the study of how objects move through the air, especially when affected by a solid object. The word comes from the Greek words aerios, which means "concerning the air", and dynamis, which means "force".  Aerodynamics is a key area of study in aeronautics and involves topics from fluid dynamics and gas dynamics. It affects anything that moves through the air, including rockets, kites, and cars.  The four forces of flight are lift, weight, thrust, and drag.... Show more

Aerodynamics is a key area of study in aeronautics and involves topics from fluid dynamics and gas dynamics. It affects anything that moves through the air, including rockets, kites, and cars. 
The four forces of flight are lift, weight, thrust, and drag. These forces determine how an object moves through the air. 
The first known use of the word "aerodynamics" was around 1829. In 1871, Francis Herbert Wenham built the first wind tunnel, which allowed for precise measurements of aerodynamic forces.
