eng.wave-power-density Calculator
Calculates wave power density (kW/m of wave crest) from significant wave height and peak period using linear wave theory. Wave power density P = ρg²H²T/32π — a 2m significant wave height with 10s period produces approximately 39 kW/m, competitive with other renewable energy sources.
Inputs
Significant Wave Height M
Vertical measurement. For health calculators, typically standing height without shoes.
Peak Period S
Time for one complete cycle (s). Period = 1 / frequency. A 50 Hz signal has a 20 ms period.
Water Density
Mass per unit volume (kg/m³). Water: 1,000. Air: 1.225. Steel: 7,850. Affects buoyancy, flow, and structural loads.
Results
