Chapter 1: Q25 DQ (page 390)

If the velocity at each point in space in steady state fluid flow is constant, how can a fluid particle accelerates?

Short Answer

Expert verified

There will be an acceleration which may be positive or negative.

Step by step solution

01

Understanding of steady state

When a systemor component does not change over time, it is known as a "steady state."

02

Solution

When a system or process does not change over time, it is known as a "steady state." In the case the velocity v1is always the same. As a result, in a steady state, all points in space are moving at the same rate as time. It does not, however, imply that all points in the fluid are moving at the same rate. v1and v2are different at different distances, and v1is not equivalent to v2. The acceleration may be either positive or negative depending on whether v1is larger than v2or vice versa.
