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.
INSTRUCTIONS: Choose units and enter the following:
2nd Pulley Diameter (D2): The calculator returns the diameter of pulley 2 in meters. However this can be automatically converted to other length units via the pull-down menu.
`D_2 = D_1*((RPM_1)/(RPM_2))`
