Double pipe heat exchangers are used
A)When heat transfer area required is very high
B)When heat transfer area required is very low, i.e. (100-200 ft2).
C)Because it occupies less floor area
D)Because it is less costly

Question

Double pipe heat exchangers are typically used when the heat transfer area requirement is relatively low, such as in the range of 100-200 square feet. This is because their design, consisting of one pipe inside another, limits the surface area available for heat exchange, making them less suitable for applications requiring large heat transfer areas.
