Pipe Class
Represents a pipe segment unit operation that models single- or multi-phase fluid flow
through one or more pipe sections with specified geometry, elevation, and thermal boundary
conditions. Pressure drop, temperature, and phase-equilibrium profiles are calculated
using a selectable two-phase flow correlation.
