## Main Question or Discussion Point

Trying to understand what will happen to the fluid in the following scenario.

Lets say there is a length of pipe with an OD of 4", what would happen if halfway along the pipe the pipe OD increased to 6" (gradual increase).

I believe the pressure of the fluid will decrease, would the flow rate also decrease.

If anyone could explain what actually happens that would be great.

Cheers
