Question

Match the pump types in Group I with their key components in Group II. \[ \begin{array}{|c|c|} \hline Group I & Group II
\hline (P) \ \text{Centrifugal pumps} & (1) \ \text{Piston rod}
(Q) \ \text{Reciprocating pumps} & (2) \ \text{Impeller}
(R) \ \text{Rotary pumps} & (3) \ \text{Gear}
(S) \ \text{Impulse pumps} & (4) \ \text{Eductor pipe}
& (5) \ \text{Hydraulic ram}
\hline \end{array} \]

• A. P-2, Q-1, R-3, S-5
• B. P-1, Q-2, R-5, S-3
• C. P-2, Q-5, R-4, S-1
• D. P-1, Q-2, R-3, S-4

Hint:

To solve pump-component matches, recall: Centrifugal → Impeller, Reciprocating → Piston rod, Rotary → Gear, Impulse → Hydraulic ram.

Answer 1

The Correct Option is A

Step 1: Centrifugal pumps.
\nThese pumps employ a rotating Impeller to propel fluid via centrifugal force. \n\[\nP \Rightarrow 2\n\] \n\n

Step 2: Reciprocating pumps.
\nTheir operation relies on the linear, back-and-forth movement of a piston connected to a Piston rod. \n\[\nQ \Rightarrow 1\n\] \n\n

Step 3: Rotary pumps.
\nThese utilize a rotating Gear or comparable component for positive displacement fluid transfer. \n\[\nR \Rightarrow 3\n\] \n\n

Step 4: Impulse pumps.
\nThis category encompasses the Hydraulic ram, which leverages water hammer effects for pumping operations. \n\[\nS \Rightarrow 5\n\] \n\n \n\[\n\boxed{P-2, \ Q-1, \ R-3, \ S-5}\n\]
