Task (1) A. You were asked to design and manufacture a plate heat exchanger, as shown in the figure, to be used in transferring heat from hot water to cold water. Which material (copper, aluminium or polyethylene) will you choose to manufacture the inner plates of the heat exchanger to obtain the highest heat transfer? Give reason for your choice. B. Will the device be lighter in weight if it is made of copper, aluminium or polyethylene? Explain your answer. C. After you completed manufacturing the heat exchanger, you noticed that its outer surface is conductive to electricity, which may be dangerous during operation. what can you do to insulate it? D. Explain two types of degradation that could happen in the heat exchanger and discuss how to prevent them? E. Briefly explain one of the degradation types in polymers.

Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.
