The 2nd Pulley Diameter equation calculates the diameter of a second pulley based on the RPMs and Diameter of the first pulley and the RPMs of the second pulley. BeltLength-illustration.png Belt length around two pulleys. 

INSTRUCTIONS: Choose units and enter the following:

  • (RPMd) The RPMs of pulley 1.
  • (Dd) The diameter of pulley 1.
  • (RPMD) The RPMs of pulley 2.

2nd Pulley Diameter (DD):   The calculator computes the diameter of pulley 2 (DD) in meters.  However this can be automatically converted to other length units via the pull-down menu.
