Question 1General Subjects - Assistant Engineer
70% to passOne of the consequences in continuing to operate a centrifugal bilge pump with the discharge valve closed, is that the _______________.
Amotor overload will open
Brelief valve will open
Cmotor will overheat
Dpump will overheat
AI Explanation
The correct answer is D) the pump will overheat. When a centrifugal bilge pump is operated with the discharge valve closed, the pump is unable to circulate water through the system. This results in the pump generating heat rather than moving water, causing the pump itself to overheat. The other options are incorrect because motor overload would not occur, the relief valve would not open (as there is no pressure buildup), and the motor would not overheat (the issue is with the pump, not the motor).
