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) refers to the difference between the low water level and the pump. Hence, P–3.
Q (Discharge lift) refers to the difference between the point of discharge and the pump. Hence, Q–1.
R (Rotary pump) works by carrying water upwards around the side of the casing and pushing it through the discharge pipe. Hence, R–4.
S (Priming of pump) involves filling the pump casing with air to remove trapped air inside, which is done before starting the pump. Hence, S–2. Thus, the correct match is (A) P–3, Q–1, R–4, S–2.
