In a dam,water falls at a rate of 1000 kg `s^(-1)` from a height of 100 m .
(b)Assuming that 60% of the energy of the falling water is converted to electrical energy,Calculate the power generated (Take g=9.8 m `s^(-2)`)

Text Solution

AI Generated Solution

To solve the problem, we need to calculate the power generated by the falling water in the dam. Let's break it down step by step. ### Step 1: Calculate the potential energy of the falling water The potential energy (PE) of the water falling from a height can be calculated using the formula: \[ PE = m \cdot g \cdot h \] where: ...
