What is the relationship between the number of cylinders in a multiplex pump and its capacity?
What is the relationship between the number of cylinders in a multiplex pump and its capacity?
- The capacity is multiplied by the number of cylinders (correct)
- The capacity remains the same regardless of the number of cylinders
- The capacity is divided by the number of cylinders
- The capacity decreases as the number of cylinders increases
Why does the velocity of the liquid inside the cylinder of a reciprocating pump vary with the crank angle?
Why does the velocity of the liquid inside the cylinder of a reciprocating pump vary with the crank angle?
- Due to changes in cylinder size
- Due to changes in velocity of the piston head (correct)
- Due to changes in temperature
- Due to changes in pressure
