The 2nd Pulley RPM calculator computes the RPMs of a second pulley based on the the RPMs and Diameter of the first pulley and the diameter of the second pulley. Belt length around two pulleys.

INSTRUCTIONS: Choose your preferred units and enter the following:

(RPM_{d}) The RPMs of the first pulley

(D_{d}) The diameter of the first pulley

(D_{D}) The diameter of the second pulley

2nd Pulley RPMs: The calculator computes the rpms (RPM_{D}) of the second pulley.
