Group Velocity of Waves Solution

STEP 0: Pre-Calculation Summary

Formula Used

Group Velocity of Waves = 0.5*Wave Speed*(1+((Wave Number for Water Wave*Coastal Mean Depth)/(sinh(Wave Number for Water Wave*Coastal Mean Depth)*cosh(Wave Number for Water Wave*Coastal Mean Depth))))
V_g = 0.5*v*(1+((k*d)/(sinh(k*d)*cosh(k*d))))
This formula uses 2 Functions, 4 Variables

Functions Used

sinh - The hyperbolic sine function, also known as the sinh function, is a mathematical function that is defined as the hyperbolic analogue of the sine function., sinh(Number)
cosh - The hyperbolic cosine function is a mathematical function that is defined as the ratio of the sum of the exponential functions of x and negative x to 2., cosh(Number)

Variables Used

Group Velocity of Waves - (Measured in Meter per Second) - The Group Velocity of Waves refers to the velocity at which the overall shape or envelope of a wave group propagates through a medium.
Wave Speed - (Measured in Meter per Second) - Wave Speed is the rate at which a wave travels through a medium, measured in distance per unit time.
Wave Number for Water Wave - Wave Number for Water Wave represents the spatial frequency of a wave, indicating how many wavelengths occur in a given distance.
Coastal Mean Depth - (Measured in Meter) - Coastal Mean Depth of a fluid flow is a measure of the average depth of the fluid in a channel, pipe, or other conduit through which the fluid is flowing.

STEP 1: Convert Input(s) to Base Unit

Wave Speed: 50 Meter per Second --> 50 Meter per Second No Conversion Required
Wave Number for Water Wave: 0.2 --> No Conversion Required
Coastal Mean Depth: 10 Meter --> 10 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_g = 0.5*v*(1+((k*d)/(sinh(k*d)*cosh(k*d)))) --> 0.5*50*(1+((0.2*10)/(sinh(0.2*10)*cosh(0.2*10))))

Evaluating ... ...

V_g = 28.6643570325866

STEP 3: Convert Result to Output's Unit

28.6643570325866 Meter per Second --> No Conversion Required

FINAL ANSWER

28.6643570325866 ≈ 28.66436 Meter per Second <-- Group Velocity of Waves

What is Wave Power and How does it Work?

Wave power is produced by the up and down motion of floating devices placed on the surface of the ocean. In other words, wind produces waves, and then waves produce energy. As the waves travel across the ocean, high-tech devices capture the natural movements of ocean currents and the flow of swells to generate power.
