A streamline is a line in flow field _________________?
  • (A)  That is traced by all the fluid particles passing through a given point
  • (B)  Along which a fluid particle travels
  • (C)  Such that at every point on it, the velocity is tangential to it
  • (D)  None of these
In turbulent flow, the__________________?
  • (A)  Fluid particles move in an orderly manner
  • (B)  Momentum transfer is on molecular scale only
  • (C)  Shear stress is caused more effectively by cohesion than momentum transfer
  • (D)  Shear stresses are generally larger than in a similar laminar flow
