What is the characteristic length of the shell-and-tube heat exchanger?

14 January 2014 1 7K Report

I want to check the nature of flow in the shell side of the shell-and-tube heat exchanger. Hence I need to know the characteristic length of the shell-and-tube heat exchanger to calculate the Rayleigh Number.
