Period of Significant Wave in SMB Prediction Method Solution

STEP 0: Pre-Calculation Summary

Formula Used

Significant Wave Period = (Wind Speed*7.540*tanh(0.077*Fetch Parameter^0.25))/[g]
T_sig = (U*7.540*tanh(0.077*φ^0.25))/[g]
This formula uses 1 Constants, 1 Functions, 3 Variables

Constants Used

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

Functions Used

tanh - The hyperbolic tangent function (tanh) is a function that is defined as the ratio of the hyperbolic sine function (sinh) to the hyperbolic cosine function (cosh)., tanh(Number)

Variables Used

Significant Wave Period - (Measured in Second) - Significant Wave Period is average time interval between successive wave crests, a key parameter in describing wave characteristics in oceanography.
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.
Fetch Parameter - Fetch Parameter is often associated with the concept of fetch, which is the unobstructed distance over which the wind blows across a body of water in a constant direction.

STEP 1: Convert Input(s) to Base Unit

Wind Speed: 4 Meter per Second --> 4 Meter per Second No Conversion Required
Fetch Parameter: 1.22 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

T_sig = (U*7.540*tanh(0.077*φ^0.25))/[g] --> (4*7.540*tanh(0.077*1.22^0.25))/[g]

Evaluating ... ...

T_sig = 0.248338901271492

STEP 3: Convert Result to Output's Unit

0.248338901271492 Second --> No Conversion Required

FINAL ANSWER

0.248338901271492 ≈ 0.248339 Second <-- Significant Wave Period
