Define aerofoil with accepted terminology with neat sketch. A wing with a span of 22m and 64 `m^2` plan area moves horizontally with a velocity of 760 kmhp. If the wing supports 280 KN, find:

• Required value of lift coefficient.
• Induced drag.

Take density of air as 0.526kg/`m^3`. [2072-Kartik ] [8]

Water flows over 0.3 m long nad 0.1 m wide flat plate at 15 m/s parallel to it. Calculate the drag force on that porti…

Distinguish between pressure and friction drag. Explain with sketches, why airfoil is designed as a streamlined body.
