Question 75General Subjects - 1st Asst/Chief
70% to passWhich of the conditions listed would indicate a large condenser tube leak within the distiller shown in the illustration? See Illustration MO-0111
AA slow continuous rise in the lube oil cooler outlet temperature indicated at device "4".
BThe activation of the salinity monitoring equipment's annunciator circuit.
CA decrease in the level of the main engine expansion tank as indicated by a low level alarm.
DAn increase in distiller output resulting from the combination of jacket water and the distillate produced.
AI Explanation
The correct answer is B) The activation of the salinity monitoring equipment's annunciator circuit. A large condenser tube leak within the distiller would allow seawater to mix with the distillate, increasing the salinity of the distilled water. This would trigger the salinity monitoring equipment's annunciator circuit, indicating the leak. The other options are incorrect because: A) A slow rise in the lube oil cooler temperature would not directly indicate a condenser tube leak. C) A decrease in the main engine expansion tank level is not related to the distiller operation. D) An increase in distiller output is not a reliable indicator of a condenser tube leak.
