The heat exchanger considered has two baffles within
the shell and the tubes arranged if five passes.
The overall heat transfer coefficient depends on the
local velocity and the resistance to flow exerted by
tubes depends on the flow direction, on the local
velocities and Reynolds numbers. They are introduced
by PLANT.
