Formula
Variables
- H — Significant wave height (m)
- Tp — Wave period (s)
- rho — Seawater density (kg/m³)
Worked example
With significant wave height = 2 m, wave period = 8 s, seawater density = 1025 kg/m³, the calculator gives wave energy flux ≈ 15.68864 kW/m.
Frequently asked questions
What is the ocean wave energy flux calculator used for?
Find the power carried by ocean waves per metre of wave crest from wave height and period. It helps with questions such as “wave energy flux”, “ocean wave power”, “wave energy per metre”.
What is the formula for the ocean wave energy flux calculation?
Wave energy flux (kW/m) = rho × GRAV × GRAV × H × H × Tp / (64 × π) / 1000. Here H is significant wave height (m), Tp is wave period (s), rho is seawater density (kg/m³).
What inputs do I need for the ocean wave energy flux calculator?
You need significant wave height in m, wave period in s, seawater density in kg/m³. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use the ocean wave energy flux calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the ocean wave energy flux result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
