Identify the correct description of streamline (laminar) flow.
(a) Laminar flow occurs when the Reynolds number of the fluid exceeds about 4000, ensuring no mixing between layers.
(b) At a given instant, the velocity has the same magnitude and direction at every point in the fluid.
(c) At every point in the fluid the velocity has constant magnitude and direction with time.
(d) The pressure at each point oscillates periodically about a mean value while the velocity remains steady.
