To calculate the motor kilowatt (kW) of a blower, you can use the formula:

[ \text{Power (kW)} = \frac{\text{Flow (m}^3/\text{h)} \times \text{Pressure (Pa)}}{3,600,000} ]

This formula considers the flow rate in cubic meters per hour and pressure in pascals. Additionally, you may need to account for efficiency by dividing the result by the motor efficiency (as a decimal). For a more precise calculation, also consider factors like system losses and the specific characteristics of the blower.
