Answer:
The diameter of the output pulley should be 192 cm
Explanation:
The given parameters are;
The diameter of the input pulley = 48 cm
The rpm of the input pulley = 1000 rpm
The rpm of the output pulley = 250 rpm
Where;
rpm = Rotation per minute
Therefore we have;
48 cm × 1000 rpm = d × 250 rpm........(1)
Where d = The diameter of the output pulley in centimetres
Solving the above equation gives;
d = 48 cm × 1000 rpm/250 rpm = 192 cm
Therefore, the diameter of the output pulley should be 192 cm.
