Steady non-uniform flow: When the velocity and other hydrodynamic parameters change from point to point in the stream but do not change with time.
Example : Flow at constant rate through a duct of non-uniform cross-section (tapering pipe) and flow in a tapering pipe with constant velocity at the inlet, velocity will change as you move along the length of the pipe toward the exit.
So correct answer is
d) Steadily decreasing flow through a reducing section.

L 2. Steady statemass balance: Water is flowing at steady state in a 0.1 meter-diameter pipe with a maximum velocity (turbulent profile) of 0.3 meters/sec. The pipe then goes through an expansion, to where it is then flowing in a 0.5 meter-diameter pipe, and the flow regime has changed from turbulent to laminar. In the second section of pipe, calculate the velocity as (a) block flow profile (Vavg), and (b) maximum velocity in laminar flow profile? HINT: you will need...
