Time required for Waves Crossing Fetch under Wind Velocity to become Fetch Limited Solution

STEP 0: Pre-Calculation Summary
Formula Used
Time required for Waves crossing Fetch = 77.23*(Straight Line Distance over which Wind Blows^0.67/(Wind Speed^0.34*[g]^0.33))
tx,u = 77.23*(X^0.67/(U^0.34*[g]^0.33))
This formula uses 1 Constants, 3 Variables
Constants Used
[g] - Gravitational acceleration on Earth Value Taken As 9.80665
Variables Used
Time required for Waves crossing Fetch - (Measured in Second) - Time required for Waves crossing Fetch under Wind Velocity to become Fetch Limited.
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.
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.
STEP 1: Convert Input(s) to Base Unit
Straight Line Distance over which Wind Blows: 15 Meter --> 15 Meter No Conversion Required
Wind Speed: 4 Meter per Second --> 4 Meter per Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
tx,u = 77.23*(X^0.67/(U^0.34*[g]^0.33)) --> 77.23*(15^0.67/(4^0.34*[g]^0.33))
Evaluating ... ...
tx,u = 139.272367550324
STEP 3: Convert Result to Output's Unit
139.272367550324 Second --> No Conversion Required
FINAL ANSWER
139.272367550324 139.2724 Second <-- Time required for Waves crossing Fetch
(Calculation completed in 00.004 seconds)

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.
