Normal Depth of Flow given Head on Entrance measured from Bottom of Culvert Solution

Follow our step by step solution on how to calculate Normal Depth of Flow given Head on Entrance measured from Bottom of Culvert?

FIRST Step Consider the formula

h = H in - (K e + 1) \cdot (v m \cdot \frac{v m}{2 \cdot [g]})

Next Step Substitute values of Variables

∴

h = 10.647m - (0.85 + 1) \cdot (10m/s \cdot \frac{10m/s}{2 \cdot [g]})

Next Step Substitute values of Constants

∴

h = 10.647m - (0.85 + 1) \cdot (10m/s \cdot \frac{10m/s}{2 \cdot 9.8066m/s²})

Next Step Prepare to Evaluate

∴

h = 10.647 - (0.85 + 1) \cdot (10 \cdot \frac{10}{2 \cdot 9.8066})

Next Step Evaluate

∴

h = 1.21462502995416m

LAST Step Rounding Answer

∴

h = 1.2146m
