Question

A one-dimensional flow is one in which _________________________

• A. Is uniform
• B. Is steady uniform
• C. Takes place in straight lines
• D. Involves zero transverse components of flow

Answer 1

Answer:

D. Involves zero transverse components of flow

One-dimensional flow involves zero transverse components of flow and can be expressed as functions of time and one space coordinate. Example: the flow in a pipe is considered one-dimensional when variations of pressure and velocity occur along the length of the pipe, but any variation over the cross-section is assumed negligible.
