- For the fluid to be in a steady-state, it cannot pile up or leak out of anywhere (what goes in at one end of the pipe must come out at the other end). In other words, the amount of time that it takes for a volume of fluid to flow past one point must equal the amount of time it takes for that same volume to flow past another point at a later time.

A steady flow is one in which conditions (velocity, pressure and cross-section) can vary from point to point, but do not change over time. In real conditions, it is very rare to have such flows with parameters that are absolutely constant over time. The parameters usually change over time bu… - 2. Unsteady Flow
If at any point of the fluid, the conditions change over time, the flow is said to be unstable. (In practice there is always a slight difference in velocity and pressure, but if the average values are constant, the flow is assumed to be constant. A constant flow can be uniform or non-uniform an…

- 1. Steady Flow
All fluids are compressible to an extent; that is, changes in pressure or temperature cause changes in density. However, in many situations the changes in pressure and temperature are sufficiently small that the changes in density are negligible. In this case the flow can be modelled as an incompressible flow. Otherwise the more general compressible flow equations …
