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 portion of the plate over which the boundary layer is laminar.
• the total drag force on both sides of the plate.

Take `rho=998` kg/`m^3` and `mu= 10^(-6)` `m^2`/s. [2074-Chaitra ] [8]

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