A seller offers an attractive discount to the plant authorities for two heat exchangers of the same property with a surface area of As = 5 m2. Since the pipe diameters in existing and new heat exchangers are the same, it is expected that the total heat transfer coefficient equation given above will also be valid for new heat exchangers. The vendor suggests that both heat exchangers can be operated in parallel in a counter-flow fashion, so that…
