Parallel & Counter Flow Heat Exchangers (LMTD): Heat Transfer for Mechanical Engineers

In this problem, we design a shell and tube heat exchanger. Specifically, we look at the difference in heat transfer area required by using a parallel or counter flow heat exchangers. Heat exchanger problems typically have one of two potential main goals: (a) find the heat transferred between two fluids, OR (b) find the area needed to achieve a required target heat transfer between two fluids. In this example, we go through a systematic process to find the area required for shell and tube heat exchangers using the log mean temperature different (LMTD) method. I believe that understanding this process will allow you to solve any heat exchanger problem.
