[PIPES]

Purpose:

Defines all pipe links contained in the network.

Format:

One line for each pipe containing:

• ID label
• ID of start node
• ID of end node
• Length, ft (m)
• Diameter, inches (mm)
• Roughness coefficient
• Minor loss coefficient
• Status (OPEN, CLOSED, or CV)

Remarks:

1. Roughness coefficient is unitless for Hazen-Williams and Chezy-Manning head loss formulas and has units of millifeet (mm) for the Darcy-Weisbach formula. Choice of head loss formula is supplied in the [OPTIONS] section.
2. Setting status to CV means that the pipe contains a check valve restricting flow to one direction.
3. If minor loss coefficient is 0 and pipe is OPEN then these two items can be dropped from the input line.
