Power Output vs Water Flow Rate
सूत्र
## How to Calculate Hydropower Output Hydropower converts the potential energy of falling water into electricity. ### Formula **Power (kW) = Flow Rate (m3/s) * Head (m) * 9.81 * Efficiency** **Annual Energy = Power * 8,760 hours * Availability Factor** - **Flow rate**: Volume of water passing through the turbine per second - **Head**: Vertical drop from intake to turbine - **Efficiency**: Modern turbines achieve 85-93%
हल किया गया उदाहरण
A hydropower site with 5 m3/s flow, 30m head, 85% turbine efficiency, 90% availability.
- 01Power: 5 * 30 * 9.81 * 0.85 = 1,250.8 kW
- 02Annual energy: 1,250.8 * 8,760 * 0.90 / 1,000 = 9,857 MWh
- 03Homes powered: 9,857 / 10.5 = 939 homes
अक्सर पूछे जाने वाले प्रश्न
What is head in hydropower?
Head is the vertical distance water falls from the intake to the turbine. Higher head means more potential energy. Run-of-river systems have low head; dam-based systems can have high head.
Is hydropower truly renewable?
Yes, hydropower uses the natural water cycle. However, large dams can impact ecosystems, fish migration, and sediment flow. Run-of-river systems have less environmental impact.
What is the capacity factor of hydropower?
Hydropower has very high capacity factors of 40-60% for conventional dams and up to 90% for some run-of-river installations, much higher than wind or solar.
