Question

Match the LIST-I with LIST-II:

• A. A-II, B-I, C-III, D-IV
• B. A-III, B-II, C-IV, D-I
• C. A-II, B-III, C-IV, D-I
• D. A-IV, B-I, C-III, D-II

Hint:

Priming = "Filling the pump." Cavitation = "Bubble trouble." Impeller = "The Spinner." Dead Zone = "Stuck still."

Answer 1

The Correct Option is C

Concept: This question covers critical terminology used in fluid transport and mixing operations, particularly concerning pumps and agitated vessels.

Step 1: Match A (Impeller).
The impeller is the rotating component of a centrifugal pump or mixer that transfers energy from the motor to the fluid (II) by accelerating it outwards.

Step 2: Match B (Cavitation).
Cavitation occurs when the local pressure drops below the vapor pressure, leading to the formation and violent collapse of vapor bubbles (III), which can damage metal surfaces.

Step 3: Match C (Priming).
Centrifugal pumps cannot pump air. Priming is the process of filling the suction pipe and casing with liquid (IV) to remove air before starting the pump.

Step 4: Match D (Dead Zone).
In mixing tanks, a "Dead Zone" refers to regions where fluid motion is poor (I) or stagnant, resulting in inadequate blending.
