Detailed Description

Vertex model to represent an isentropic compressor
Has an one or more inlets, and one outlet.

#include <libpf/units/Compressor.h>

Remarks

Only supports Flash configuration (option) = {D,P}H Pressure option:

D assumes deltaP is fixed
P assumes the outlet pressure is fixed

Warning: Simultaneous resolution: supported; Thread safe:; Extendable:; Platform dependencies:
