Question

For the flow to occur between two points in a pipeline, the differential pressure between these points should be more than

• A. surface friction
• B. viscosity force
• C. frictional force
• D. All of the above

Answer 1

Answer:

D. All of the above

To allow flow between two points in a pipeline, the differential pressure between them must be greater than surface friction, viscosity force, and frictional force. This is because the pressure force of the fluid needs to overcome these resistances.
