Partialy filled pipe
Partialy filled pipe
(OP)
I have a couple related questions regarding typical pipe flow in an open system.
1. In a pipe line, how can you predict if the pipe will be full or not? The flow calculations would seem to change radically based on the assumption that the pipe is filled vs. not filled.
2. Assume there is a long pipeline (6 miles or so), of constant diameter but with elevation changes. If there is a cross section of that pipe where the pipe is full, will it be full everywhere?
My original belief was that it should be, but then I realized that even though the volumetric flow is the same at any point, you could have a higher velocity coupled with a smaller area to produce the same flow.
The assumption is that as the pipe is rising in elevation, the pipe is fuller than it is on the downward side.
