How far from the engine exhaust system output must evaporator condensate drains terminate?

The correct answer indicates that evaporator condensate drains must terminate at least 3 feet or more from the engine exhaust system output to ensure proper functioning and safety. This distance is essential to avoid potential contamination and overheating issues.

If condensate drains are too close to the exhaust output, there is a risk that the exhaust heat could cause the condensate to vaporize prematurely, leading to inefficiency in the cooling system. Additionally, any potential harmful exhaust gases or contaminants could be drawn back into the system if the drains are positioned too close, which can pose safety concerns for crew and passengers.

By maintaining a distance of at least 3 feet, the integrity of the cooling and exhaust systems is better protected, thereby promoting efficient operation and reducing the risk of backflow of exhaust gases. This guideline adheres to established safety standards within marine systems design.
