Water falls from a height of $60\text{m}$ at the rate of $15\text{kg/s}$ to operate a turbine. The losses due to frictional force are $10\%$ of the input energy. How much power is generated by the turbine? ($g=10{\text{m/s}}^2$)

1. A
   $12.3\text{kW}$
2. B
   $7.0\text{kW}$
3. C
   $10.2\text{kW}$
4. D
   $8.1\text{kW}$
