What is the formula for calculating piston speed in a refrigeration system?

The formula for calculating piston speed in a refrigeration system is accurately represented by the option that uses the formula PS = (2 x Stroke x RPM)/12. This formulation is derived from the principles of mechanical motion, where the piston travels forward and backward within the cylinder.

In this context, "Stroke" refers to the distance the piston travels in one direction, and since the piston moves back and forth, the total distance covered in one complete cycle is twice the Stroke length. Multiplying by the RPM (Revolutions Per Minute) gives the distance traveled per minute, and then dividing by 12 converts the result into feet per minute, assuming the Stroke is measured in inches.

This formula effectively captures the dynamics of a reciprocating compressor's operation, allowing for an accurate calculation of the speed at which the piston moves. Understanding this concept is crucial for those working with refrigeration systems, as it impacts system performance and efficiency.
