Question

Match List-I with List-II. List-I Terminology: A. Capacity of pump, B. Suction lift, C. Static suction lift, D. Suction head. List-II Detail: I. When the source of water supply is above the centre line of the pump, II. The volume of water pumped per unit time, III. When the source of water supply is below the centre line pump, IV. The vertical distance from the free suction water level to the centre line of the pump.

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

Hint:

Suction lift is used when water source is below pump centre line, while suction head is used when water source is above pump centre line.

Answer 1

The Correct Option is B

Concept:
Pump terminology is based on discharge, water level position and vertical distance of suction.

Step 1: Capacity of pump.
Capacity of pump means the volume of water pumped per unit time. \[ A\rightarrow II \]

Step 2: Suction lift.
Suction lift occurs when the source of water supply is below the centre line of the pump. \[ B\rightarrow III \]

Step 3: Static suction lift.
Static suction lift is the vertical distance from the free suction water level to the centre line of the pump. \[ C\rightarrow IV \]

Step 4: Suction head.
Suction head occurs when the water source is above the centre line of the pump. \[ D\rightarrow I \] Therefore: \[ A-II,\ B-III,\ C-IV,\ D-I \] \[ \therefore \text{Correct Answer is (B)} \]
