3.6 Multi-pass
Multi-pass sections can be created by using turning plates with 1, 2 or 3
unholed ports. The main purpose is to change the flow direction of one or both
fluids.
An example of where multi-pass can be used is in processes that require
longer heating periods if the media requires slower heating.
