Root Mean Square Wave Height at Breaking given Longshore Current at Mid-Surf Zone Solution

Follow our step by step solution on how to calculate Root Mean Square Wave Height at Breaking given Longshore Current at Mid-Surf Zone?

FIRST Step Consider the formula
Hrms=(Vmid1.17sin(α)cos(α))0.5[g]
Next Step Substitute values of Variables
Hrms=(1.09m/s1.17sin(60°)cos(60°))0.5[g]
Next Step Substitute values of Constants
Hrms=(1.09m/s1.17sin(60°)cos(60°))0.59.8066m/s²
Next Step Convert Units
Hrms=(1.09m/s1.17sin(1.0472rad)cos(1.0472rad))0.59.8066m/s²
Next Step Prepare to Evaluate
Hrms=(1.091.17sin(1.0472)cos(1.0472))0.59.8066
Next Step Evaluate
Hrms=0.149571663742143m
LAST Step Rounding Answer
Hrms=0.1496m
