Horsepower (\( HP \)):

\[ HP = \frac{Q \cdot H \cdot F}{4562} \]

Where:

• \( HP \) is the power requirement, in horsepower (hp).
• \( Q \) is the bucket elevator capacity, in kilograms per minute (kg/min).
• \( H \) is the lift, in meters (m).
• \( F \) is the load factor: 1.5 for elevator loaded in down side; 1.2 for elevator loaded in up side.
