Head loss by Manning Formula given Radius of Pipe Solution

Follow our step by step solution on how to calculate Head loss by Manning Formula given Radius of Pipe?

FIRST Step Consider the formula

h f = \frac{Lp' \cdot {(n \cdot v f)}^{2}}{0.157 \cdot {(2 \cdot R)}^{\frac{4}{3}}}

Next Step Substitute values of Variables

∴

h f = \frac{4.9m \cdot {(0.009 \cdot 11.96m/s)}^{2}}{0.157 \cdot {(2 \cdot 200mm)}^{\frac{4}{3}}}

Next Step Convert Units

∴

h f = \frac{4.9m \cdot {(0.009 \cdot 11.96m/s)}^{2}}{0.157 \cdot {(2 \cdot 0.2m)}^{\frac{4}{3}}}

Next Step Prepare to Evaluate

∴

h f = \frac{4.9 \cdot {(0.009 \cdot 11.96)}^{2}}{0.157 \cdot {(2 \cdot 0.2)}^{\frac{4}{3}}}

Next Step Evaluate

∴

h f = 1.22696022450347m

LAST Step Rounding Answer

∴

h f = 1.227m
