Text Solution

The streamline flow is a steady flow in which each particle of the liquid has at any point the same magnitude and direction of velocity as its preceding particles had at that point. On the other hand, the turbulent flow is highly unsteady and disordered flow in which the velocity of the particles at any point varies with time both in magnitude and direction.
