A pump draws water $\left(\right.$ density $\left.=1000 \mathrm{~kg} \cdot \mathrm{m}^{-3}\right)$ at a steady rate of $10 \mathrm{~kg} \cdot \mathrm{s}^{-1}$. The pressures at the suction and discharge sides of the pump are $-20 ~ \mathrm{kPa}$ (gauge) and $350 ~ \mathrm{kPa}$ (gauge), respectively. The pipe diameters at the suction and discharge side are $70 \mathrm{~mm}$ and $50 \mathrm{~mm}$, respectively. The suction and discharge lines are at the same elevation, and the pump operates at an efficiency of $80 \%$. Neglecting frictional losses in the system, the power (in $\mathrm{kW}$ ) required to drive the pump is__________________(rounded off to two decimal places).
