Work, Energy and Power
question_answer
Water is falling at the rate of \[1000\,\,kg\] per second. The height of the fall is about\[100\,\,m\]. The potential energy of water when it falls on the blades will be conveyed to them and \[P.E.\] is converted into \[K.E.\] of blades. Estimate the power that could be generated, if energy is not lost otherwise (Take the value of gas\[10\,\,m{{s}^{-2}}\]).
