A steady flow is one in which all conditions at any point in a stream remain constant with respect to time. ... But if this rate of change of pressure and velocity are equal on both sides of a constant average value, the flow is steady flow. The exact term use for this is mean steady flow.

What does a steady flow mean?

A steady flow is one in which all conditions at any point in a stream remain constant with respect to time. ... The exact term use for this is mean steady flow. Steady flow may be uniform or non-uniform. Uniform flow. A truly uniform flow is one in which the velocity is same at a given instant at every point in the fluid.

What is steady and non steady flow?

A flow that is not a function of time is called steady flow. Steady-state flow refers to the condition where the fluid properties at a point in the system do not change over time. Time dependent flow is known as unsteady (also called transient). ... This roughly means that all statistical properties are constant in time.
