Question 418General Subjects - Assistant Engineer
70% to passIf a centrifugal pump were continually operated with the discharge valve closed the _______________.
Amotor controller overload would open
Bpump would eventually overheat
Crelief valve would continuously cycle open
Dmotor would overheat
AI Explanation
The correct answer is B) the pump would eventually overheat. When a centrifugal pump is operated with the discharge valve closed, the pump is unable to circulate fluid and generate flow. Without any flow, the fluid in the pump would recirculate and generate heat due to the work done by the pump impeller. This would cause the pump and the fluid within it to overheat, potentially leading to damage to the pump and other components. The other options are incorrect because they do not directly address the issue of overheating caused by the lack of flow through the pump.
