    Water is flowing on the blades of a turbine at a rate of 100 kg/s from a certain spring. If the height of the spring be 100 m, the power transferred to the turbine will be :

    A)  100 W        

    B)  1 kW

    C)  10 kW        

    D)  100 kW

    Correct Answer: D

    Solution :

    Key Idea: Power is the rate of energy transferred. Power \[=\frac{energy}{time}\] or            \[p=\frac{mgh}{t}\] ... (i) Here, \[\frac{m}{t}=100\,kg/s,\,g=10\,m/{{s}^{2}},\,h=100\,m\] Substituting the values, we obtain \[p=100\times 10\times 100={{10}^{5}}W=100\,kW\]
