Question

Match the items in Group-I with the corresponding statements in Group-II.

 

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

Hint:

Suction lift refers to the vertical distance between the water level and the pump, while discharge lift refers to the vertical distance between the pump and the point of discharge.

Answer 1

The Correct Option is A

P (Suction lift) is defined as the vertical distance from the low water level to the pump. This corresponds to P–3.
\n Q (Discharge lift) is defined as the vertical distance from the discharge point to the pump. This corresponds to Q–1.
\n R (Rotary pump) operates by transferring water along the side of the casing to the discharge pipe. This corresponds to R–4.
\n S (Priming of pump) is the process of filling the pump casing with liquid (typically water) to displace trapped air before operation. This corresponds to S–2.
\n\nTherefore, the correct pairing is P–3, Q–1, R–4, S–2.
