Air is flowing over flat plate 500mm long and 60mm wide with viscosity of air as 0.15 x 10-4 m2/s . Find : i) Boundary layer thickness at tha end of the plate. ii) Shear stress at 200mm from the leading edge. iii) Drag force on one side of the plate.Take velocity of profile over plate as: $\frac{\mu}{U}=Sin(\frac{\pi}{2}.\frac{y}{\delta})$

Take density of air $1.24 kg/m^3$.
