Basic design concept

You are to specify the number of tubes and their geometric layout (how many rows top to bottom) how long (side to side) and how many deep (in the flow direction) and the fin spacing.

The spacing, diameter, and composition of the tubes is “set”

Technical and Economic Constraints are given.

“Governing” Equations

Empirical equations based on your company’s vast experience designing these kinds of systems are supplied.
