Question

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R Assertion A: In pumps, suction lift exists when the source of water supply is below the centre line of pump. Reason R: Total static suction lift is the sum of static suction lift minus friction losses, entrance losses in the suction piping. In the light of the above statements, choose the most appropriate answer from the options given below

• A. Both A and R are correct and R is the correct explanation of A
• B. Both A and R are correct but R is NOT the correct explanation of A
• C. A is correct but R is not correct
• D. A is not correct but R is correct

Hint:

Important pump terminology: \[ \boxed{ \text{Suction lift} \Rightarrow \text{Source below pump centerline} } \] \[ \boxed{ \text{Total suction head} = \text{Static lift} + \text{Losses} } \] Losses include:
• Friction losses
• Entrance losses
• Pipe losses

Answer 1

The Correct Option is B
