Belt Speed

The Speed of a Belt calculator computes the speed at which a linear length of belt travels around a pulley  based on the diameter (D)  of the pulley and the rotation rate (R).Belt

INSTRUCTIONS: Choose units and enter the following:

• (D) Diameter of Pulley
• (RPM) Rotation Rate

Belt Speed (BS): The calculator computes the belt speed in feet per second.  However, this can be automatically converted to other velocity units via the pull-down menu.

The Math

The formula for the speed of the belt  is: 

               BS = (D •π • R)/(2π)  = ½•D•RPM

where:

• BS is the Belt Speed
• D is the diameter of the pulley
• RPM is the rotation rate (rpms) of the pulley
