GATE Civil Engineering (CE) 2018 Shift 2 Solved Paper

A flocculation tank contains $1800{\mathit{m}}^3$ of water, which is mixed using paddles at an average velocity gradient $\mathit{G}$ of $100/\mathit{s}$. The water temperature and the corresponding dynamic viscosity are ${30}^{-}\mathit{C}$ and $0.798\times {10}^{-3}\mathit{N}\mathit{s}/{\mathit{m}}^2$, respectively. The theoretical power required to achieve the stated value of $\mathit{G}$ (in $\mathit{k}\mathit{W}$, up to two decimal places) is
