Length of Opening given Runoff Quantity with Full Gutter Flow Solution

Follow our step by step solution on how to calculate Length of Opening given Runoff Quantity with Full Gutter Flow?

FIRST Step Consider the formula

L o = \frac{Q ro}{0.7 \cdot {(a + y)}^{\frac{3}{2}}}

Next Step Substitute values of Variables

∴

L o = \frac{329ft³/s}{0.7 \cdot {(4ft + 7.117ft)}^{\frac{3}{2}}}

Next Step Convert Units

∴

L o = \frac{9.3162m³/s}{0.7 \cdot {(1.2192m + 2.1693m)}^{\frac{3}{2}}}

Next Step Prepare to Evaluate

∴

L o = \frac{9.3162}{0.7 \cdot {(1.2192 + 2.1693)}^{\frac{3}{2}}}

Next Step Evaluate

∴

L o = 2.13372719983356m

Next Step Convert to Output's Unit

∴

L o = 7.0004173222606ft

LAST Step Rounding Answer

∴

L o = 7.0004ft
