Question 253General Subjects - QMED

The correct answer is A) Suction head. The suction head refers to the pressure of the liquid entering the centrifugal pump. This pressure is an important factor in the pump's performance, as it affects the pump's ability to draw in and move the liquid. The suction head is measured at the pump's inlet and represents the pressure that the pump must overcome to lift the liquid into the impeller. The other options are incorrect because: B) Pump head refers to the overall pressure increase across the pump. C) Discharge head refers to the pressure of the liquid exiting the pump. D) Total head is the combination of the suction head, pump head, and discharge head.
