A flocculation tank used for water treatment has a velocity gradient $(G)$ of $800 \mathrm{~s}^{-1}$. The volume of the tank is $40 \mathrm{~m}^{3}$. The dynamic viscosity of water is $9 \times 10^{-4} \mathrm{~N} \cdot \mathrm{s} / \mathrm{m}^{2}$. The theoretical power required to maintain the given velocity gradient is__________$\text{kW}$ $\text{(rounded off to the nearest integer)}$.
