Surface unevenness Solution

Follow our step by step solution on how to calculate Surface unevenness?

FIRST Step Consider the formula

S sd = 1.11 \cdot ({Z w}^{0.384})

Next Step Substitute values of Variables

∴

S sd = 1.11 \cdot ({10m³/s}^{0.384})

Next Step Prepare to Evaluate

∴

S sd = 1.11 \cdot (10^{0.384})

Next Step Evaluate

∴

S sd = 2.68734224187716m

LAST Step Rounding Answer

∴

S sd = 2.6873m
