Tidal Power Hydropower Calculator

Formulas

The Tidal Power Hydropower Calculator uses a simplified formula based on potential energy from tidal range:

• Power (\( P \)) = \( \eta \times \rho \times g \times h \times Q \)
• Where:
  • \( \eta = \text{Efficiency (as a decimal, e.g., 80% = 0.80)} \)
  • \( \rho = \text{Water density (1000 kg/m³)} \)
  • \( g = \text{Acceleration due to gravity (9.81 m/s²)} \)
  • \( h = \text{Tidal range (height difference in meters)} \)
  • \( Q = \text{Flow rate (volume of water in m³/s)} \)

How to Use

1. Enter the tidal range (in meters) in the “Tidal Range” field.
2. Enter the flow rate (in m³/s) in the “Flow Rate” field.
3. Enter the efficiency (in percent) in the “Efficiency” field.
4. Optionally, click an adjust button to set typical values (e.g., Low Range).
5. Click “Calculate Power” to see your results.
6. Scroll to the “Results” section for detailed calculations.
7. Use the share buttons to share your power output or embed the calculator.

Examples

1. Example 1: Tidal Range = 2m, Flow Rate = 5 m³/s, Efficiency = 80%
   Power = 0.80 × 1000 × 9.81 × 2 × 5 = 78,480 W (78.48 kW)
2. Example 2: Tidal Range = 5m, Flow Rate = 2 m³/s, Efficiency = 85%
   Power = 0.85 × 1000 × 9.81 × 5 × 2 = 83,385 W (83.39 kW)
3. Example 3: Tidal Range = 1m, Flow Rate = 10 m³/s, Efficiency = 75%
   Power = 0.75 × 1000 × 9.81 × 1 × 10 = 73,575 W (73.58 kW)
