A water treatment plant is required to process 28800 m³/d of raw water (density = 1000 kg/m³, kinematic viscosity = 10^-6m²/s). The rapid mixing tank imparts a velocity gradient of 900 s^-1 to blend 35 mg/I of alum with the flow for a detention time of 2 minutes. The power input (W) required for rapid mixing is
