Question
B) for the velocity profiles given below, state whether the boundary layer has separated or on the verge of
separation or will remain attached (
i) u/U=2(y/8) -(y/8)² ii) u/U=-2(y/8) +0.5(y/8)³
iii) u/U-1.5(y/8) +0.5(y/8)³
Q3: Find the displacement, momentum thickness and energy thickness for the velocity distribution in the
boundary layer: F
u/U=0.5(y/8) + 1.5(y/8)³
Q4: A) Find the velocity distribution and expression of the maximum velocity and shear stress for a flow
between two stationary plates. C
B) A laminar flow of oil between two horizontal fixed parallel plates with a maximum velocity 2 m/s and
100mm apart. Canulate the pressure gradient and shear stress. Take µ-2.4525 s/m².
