Word Count : 274
To solve this numerically, we use the following formula to calculate the power that can be developed by a hydroelectric station: \[ P = \frac{{\rho \cdot g \cdot Q \cdot H \cdot \eta}}{{1000}} \] Where: - \( P \) = Power developed (in kW) - \( \rho \) = Density of water (\( 1000 \, \text{kg/m}^3 \) for fresh water) - \( g \) = Acceleration due to ______ _______ ____ ____ ______ ___ ______ _________ ____ _________.
