2.5 Chain Speed

In order to calculate the speed of a chain in feet per minute (fpm), we need the following information: 

  1. The number of teeth on the sprocket. 
  2. The shaft rpm of the sprocket. 
  3. The pitch of the chain in inches. 

Here’s an example: 

Now, here is the formula to solve the example above: 

Use the formula above to find the speed of the following chain:
