Area is the Total Effective Tube Area

The end result of choosing the most advantageous combination of all factors is the most economical value for A, the effective tube surface area. This area gives an answer to the question: “How big a unit must we provide in order to meet our requirement?”

The effective tube area is that portion within the shell exposed to the shell side fluid.

It is common practice to figure the area in square feet using the outside diameter of the tubing instead of an inside or mean diameter. This is merely for convenience, because the area per foot of a given O.D. tube is the same for all wall thickness.
