The image above represents r.p.m of driven pulley. To calculate the r.p.m of driven pulley, three essential parameters are needed and these parameters are Diameter of Driven Pulley (Db), r.p.m. of Driver Pulley (ra) and Diameter of Driver Pulley (Db).
The formula for calculating r.p.m of driven pulley:
rb = (Da x ra/Db
Where:
rb = r.p.m. of Driven Pulley
Da = Diameter of Driver Pulley
ra = r.p.m. of Driver Pulley
Db = Diameter of Driven Pulley
Let’s solve an example;
Given that the diameter of driver pulley is 10, the r.p.m of driver pulley is 4 and the diameter of driven pulley is 6. Find the r.p.m of driven pulley?
This implies that;
Da = Diameter of Driver Pulley = 10
ra = r.p.m. of Driver Pulley = 4
Db = Diameter of Driven Pulley = 6
rb = (Da x ra/Db
rb = (10 x 4)/6
So, rb = 40/6
rb = 6.67
Therefore, the r.p.m of driven pulley is 6.67 Hz.
