Hydraulic Radius of Open Channel Solution

Follow our step by step solution on how to calculate Hydraulic Radius of Open Channel?

FIRST Step Consider the formula

R H(rect) = \frac{B rect \cdot D f}{B rect + 2 \cdot D f}

Next Step Substitute values of Variables

∴

R H(rect) = \frac{10.4m \cdot 5.2m}{10.4m + 2 \cdot 5.2m}

Next Step Prepare to Evaluate

∴

R H(rect) = \frac{10.4 \cdot 5.2}{10.4 + 2 \cdot 5.2}

LAST Step Evaluate

∴

R H(rect) = 2.6m
