Wind Speed given Time required for Waves crossing Fetch under Wind Velocity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Wind Speed = ((77.23*Straight Line Distance over which Wind Blows^0.67)/(Time required for Waves crossing Fetch*[g]^0.33))^(1/0.34)
U = ((77.23*X^0.67)/(t_x,u*[g]^0.33))^(1/0.34)
This formula uses 1 Constants, 3 Variables

Constants Used

[g] - Gravitational acceleration on Earth Value Taken As 9.80665

Variables Used

Wind Speed - (Measured in Meter per Second) - Wind Speed is a fundamental atmospheric quantity caused by air moving from high to low pressure, usually due to changes in temperature.
Straight Line Distance over which Wind Blows - (Measured in Meter) - Straight Line Distance over which Wind Blows is defined as total stretch of wind motion in a straight line influencing other parameters of the wave.
Time required for Waves crossing Fetch - (Measured in Second) - Time required for Waves crossing Fetch under Wind Velocity to become Fetch Limited.

STEP 1: Convert Input(s) to Base Unit

Straight Line Distance over which Wind Blows: 15 Meter --> 15 Meter No Conversion Required
Time required for Waves crossing Fetch: 140 Second --> 140 Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

U = ((77.23*X^0.67)/(t_x,u*[g]^0.33))^(1/0.34) --> ((77.23*15^0.67)/(140*[g]^0.33))^(1/0.34)

Evaluating ... ...

U = 3.93916236256463

STEP 3: Convert Result to Output's Unit

3.93916236256463 Meter per Second --> No Conversion Required

FINAL ANSWER

3.93916236256463 ≈ 3.939162 Meter per Second <-- Wind Speed

What is Fetch Length?

In oceanography wind fetch, also known as fetch length or simply fetch, is the length of water over which a given wind has blown without obstruction. Fetch, area of ocean or lake surface over which the wind blows in an essentially constant direction, thus generating waves. The term also is used as a synonym for fetch length, which is the horizontal distance over which wave-generating winds blow.
