The velocity distribution for flow over a plate is given by u = 0.5y - y2 where ‘u’ is the velocity in m/s at a distance ‘y’ meter above the plate. If the dynamic viscosity of the fluid is 0.9 N-s/m2, then what is the shear stress at 0.20 m from the boundary?
Detailed Solution for Test: Boundary Layer Theory - 1 - Question 6

Shear stress τ =  = μ (0.5 - 2y)
at y = 0.2 m,
τ = 0.9 x (05 - 2 x 0.2) = 0.09 N/m2

Detailed Solution for Test: Boundary Layer Theory - 1 - Question 7

For a well streamlined body the separation occurs only at the downstream end. As such the wake in this case is extremely small. Flence the pressure drag of such objects is very small fraction of that of the disc. However, the frictional drag of streamlined bodies is considerably large than that of the sphere, since there being more surface area in contact with the flow. Furthermore, for well streamlined objects friction drag is usually larger than pressure drag, but both are so small that their total drag is only about one-fortieth (1/40) of that of the disc.
