thermal‚ mechanical and hydraulic design response report to a heat exchanger problem where ethylene glycol and a poor quality feed of water are put through a shell and tube exchanger with the objective of cooling the ethylene glycol feed. A shell and tube exchanger was chosen over several other exchangers due to its high efficient performance and its relative ease of maintenance in processing these fluids. From the data given and specific heat capacity researched for ethylene glycol‚ a MatLab script
