Extension of rapid sizing algorithm for shell-and-tube heat exchangers with tube-side pressure drop constraint and multipasses (Part B)

There are occasions in which process engineers need approximate estimates o f the exchanger size rather than full detailed designs. These situations ar e often accompanied by a need for speed. This paper provides a simple proce dure for exchanger sizing which is rapid and with reasonable accuracy. The methodology involved is described in detail here and it is shown that the p rocedure can be applied to pure counterflow and also for multipass exchange rs.
