Question

The slip of a reciprocating pump is defined as

• A. Product of theoretical discharge and the actual discharge
• B. The ratio of actual discharge to the theoretical discharge
• C. Difference between theoretical discharge and the actual discharge
• D. Sum of actual discharge and the theoretical discharge

Answer 1

The correct option is C

Difference between theoretical discharge and the actual discharge

Explanation for Correct Options:

Option (C):

1. Reciprocating pump-It is a displacement pump that utilizes a piston to change the cavity's volume and produces a pressure differentially
2. Discharge of reciprocating pump-It is defined as the work done by the pump per unit of time
3. Theoretical discharge is the value that comes out after calculations made on paper ($Q_{th}$)
4. Actual discharge is the amount that comes out after the procedure takes place( $Q_{act}$)
5. Slip of the reciprocating pump is defined as the difference between theoretical discharge and the actual discharge.

$Slipofreciprocating=Q_{th}-Q_{act}$

Explanation for Incorrect Options:

Option (A):

The slip of the reciprocating pump is defined as the difference between theoretical discharge and the actual discharge and not their product. So, this option is incorrect.

Option (B):

The slip of the reciprocating pump is defined as the difference between theoretical discharge and the actual discharge and not their ratio. So, this option is incorrect.

Option (D):

The slip of the reciprocating pump is defined as the difference between theoretical discharge and the actual discharge and not their sum. So, this option is incorrect.

Therefore, the correct option is (C).
