Setdown at Breaker Point at Still-Water Shoreline Solution

Follow our step by step solution on how to calculate Setdown at Breaker Point at Still-Water Shoreline?

FIRST Step Consider the formula

η b = η s - (\frac{1}{1 + (\frac{8}{3 \cdot {Υ b'}^{2}})}) \cdot d b

Next Step Substitute values of Variables

∴

η b = 53m - (\frac{1}{1 + (\frac{8}{3 \cdot {7.91}^{2}})}) \cdot 55m

Next Step Prepare to Evaluate

∴

η b = 53 - (\frac{1}{1 + (\frac{8}{3 \cdot {7.91}^{2}})}) \cdot 55

Next Step Evaluate

∴

η b = 0.248289894499003m

LAST Step Rounding Answer

∴

η b = 0.2483m
