Consider flow of oil and water through a channel; the boundary conditions at the interface are
  • a)
    velocity and shear stress are continuous
  • b)
    shear stress is continuous and velocity is discontinuous
  • c)
    shear stress is zero and velocity is continuous
  • d)
    shear stress is zero
Correct answer is option 'A'. Can you explain this answer?

Since the interface will have a defined velocity (Vi). The velocity of a particle just below the interface (in water) has to be the same as the velocity of the particle just above the interface (in oil), otherwise the interface will deform due to uneven velocity. Assuming the flow is fully developed. The shear stress (τ) just above and below the interface must be the same, or there will be a net force on the interface which will accelerate the interface. Consider an element at the interface.
For uniform velocity (τoil = τwater ) at interface Since τ is equal at interface in both the liquids, shear stress is continuous.
Since the interface has a defined velocity, velocity will be continuous.
