True or False? In two-pipe hydronic reverse return systems, each pipe circuit has the same length supply and return line.

In a two-pipe hydronic reverse return system, the design ensures that each pipe circuit has equal lengths for both the supply and return lines. This configuration is significant because it promotes balanced flow among the various circuits within the system. Since the flow resistance is uniform when the lengths are equal, it helps maintain consistent heating or cooling throughout the system.

When the lengths of the supply and return lines are matched, as is the case in a well-designed reverse return system, it allows for each circuit to have the same hydraulic characteristics, minimizing the potential for issues such as uneven temperature distribution or imbalanced flow rates. This design approach is critical for achieving optimal efficiency and performance in hydronic heating and cooling systems.

Other responses, while related to system design, do not specifically address the principle behind the two-pipe reverse return design, hence leading to an inaccurate affirmation about the system's characteristics.
