The power output of a hydro plant is calculated using the formula P = ρ g Q H e, where each term represents a specific parameter affecting power generation. P represents the power output, typically measured in watts (W) or kilowatts (kW). ρ (rho) represents the density of water, typically around 1000 kg/m³ for freshwater, but this can vary slightly with temperature. g represents the acceleration due to gravity, which is approximately 9.81 m/s².
