Final answer:
The number of cylinders would not help determine compressor displacement.
Step-by-step explanation:
The **number of cylinders** would not help determine compressor displacement.
Compressor displacement refers to the volume of air or gas that the compressor can displace or deliver in a single revolution or cycle. The length of the piston, revolution per minute (RPM), and diameter of the piston are all factors that contribute to the displacement of the compressor. However, the number of cylinders does not directly affect the displacement of the compressor. Instead, it determines the overall capacity and power output of the compressor.
