Question 387General Subjects - Assistant Engineer

The correct answer is B) Suction head. The suction head refers to the pressure of the liquid entering the centrifugal pump. This pressure is important as it determines the pump's ability to draw the liquid into the impeller. A high suction head indicates a higher pressure at the pump inlet, which helps the pump operate more efficiently. The other options are incorrect because: A) Discharge head refers to the pressure of the liquid leaving the pump. C) Pump head is a general term that encompasses both the suction head and the discharge head. D) Total head is the combination of the suction head and the discharge head.
