A tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow — liquids and gases (fluids).
Usually built of metallic, ceramic or plastic material.
Normal pipe has a constant cross-section area
A, meaning that it is not varying along the pipe length
l:
| (1) | A(l) = A = {\rm const} \Leftrightarrow \frac{\partial A}{\partial l} = 0 |
The assembly of interconnected pipes is called a Pipeline.
In many Pipe Flow Simulation non-circular pipes can be accurately modelled as circular pipe with hydraulic diameter
D_H.
