gravity 0.9 and kinematic viscosity 101 172/6, The fluid is moving with a
velocity of 6 m/s. Determine (i) boundary layer thickness and (ii) shear stress at
the end of the plate. Also find the drag force on one side of the plate

Explain the phenomenon of boundary layer separation

Explain ‘“Moody’s Chart”. What is its use in pipe flow?

Two parallel plates kept 0.1 m apart have laminar flow of oil between them
with a maximum velocity of 1.5 m/s. Calculate the discharge per unit width, the
shear stress at the plates, the difference in pressure between two points 20 m
apart, the velocity gradient at the plates and velocity at 0.02 m from the plate.
Take viscosity of oil to be 2.453 Ns/m?.

Explain with neat sketches the growth of boundary layer over a flat plate
