Water falls from a height of $60 m$ at the rate of $15 kg / s$ to operate a turbine. The losses due to frictional forces are $10%$ of energy. How much power is generated by the turbine? $(g = 10 m / s^{2})$ NEET 2008 (Screening)

Options:

Answer:

Solution:

Power generated by the turbine is, $P_{gene rated} = P_{input} \times \frac{90}{100} = \frac{M g h}{t} \times \frac{90}{100}$ Putting the given values $\frac{M}{t} = 15 kg / s, g = 10 m / s^{2}, h = 60 m P_{generated} = (15 \times 10 \times 60) \times \frac{90}{100} = 8.1 kW$
