Velocity ratio = diameter of the driven pulley ÷ diameter of the driver pulley
If you know the velocity ratio and the input speed of a pulley system, you can calculate the output speed using the formula:
Output speed = input speed ÷ velocity ratio
Worked example
Velocity ratio = 120mm ÷ 40mm = 3
Output speed = 100rpm ÷ 3 = 33.3 rpm
