*2.4.1 Diameter of driver pulley*

$$\mathbf{D} = (\mathbf{110-113}) \times \sqrt[3]{\frac{\mathbf{P}(\mathbf{KW})}{2\pi \mathbf{N}\_{\text{max}}}} \tag{14}$$
 
$$\mathbf{D} = \mathbf{113} \times \sqrt[3]{\frac{.75}{2 \times \pi \times \mathbf{1380}}}.$$

D = 5.3 cm.

D = 6 cm (consider) = 60 mm (**Figure 9**).
