Streamline flow of the liquid is the flow in which every particle of the liquid follows the same path as the path of the preceeding particle and has the same velocity as that of the preeding particle while crossing through the same points. Two streamlines can never cut each other. When a liqui moves randomly or in irregular manner such that its velocity becomes greater than the critical velocity than the flow is turbulent flow. Critical velocity is given by `v_(c)=(K eta)/(pr)`.
For flow to be streamlined the

Options

A. critical velocity should be large.
B. critical velocity should be amall.
C. radius of the tube should be very large.
D. coefficient of viscosity should be small

Answer

A
