Velocity ratio:
- The ratio of the diameter of the follower/driven pulley to the diameter of the driver pulley is called its speed/velocity ratio.
Velocity ratio: \(\frac{N_1}{N_2}~=~\frac{D_2}{D_1}\)
Where, N1 = Speed of the driver, N2 = Speed of the driven, D1 = Diameter of the driver pulley, D2 = Diameter of the driven pulley
Calculation:
Given:
D1 = 100 mm, N2 = 1400 rpm, N1 = 1400 rpm
∵ Velocity ratio: \(\frac{N_1}{N_2}~=~\frac{D_2}{D_1}\)
⇒ \(\frac{1400}{1400}~=~\frac{D_2}{100}\)
⇒ D2 = 100 mm = diameter of the driven pulley
