For a reciprocating pump, the indicator diagram is the graph between the________________?
Correct answer: B. Volume swept by piston for one complete revolution and the pressure in the cylinder
- A. Discharge and overall efficiency
- B. Volume swept by piston for one complete revolution and the pressure in the cylinder
- C. Angle swept by the crank pin at any instant and the discharge
- D. None of these
Explanation
An indicator diagram records cylinder pressure against piston displacement, which can be expressed as the volume swept by the piston. Its enclosed area represents the work done during the pump cycle.
