Detailed Description

Class ConstPressureReactor is a class for constant-pressure reactors.

The reactor may have an arbitrary number of inlets and outlets, each of which may be connected to a "flow device" such as a mass flow controller, a pressure regulator, etc. Additional reactors may be connected to the other end of the flow device, allowing construction of arbitrary reactor networks.
