Length of Opening given Runoff Quantity with Full Gutter Flow Solution

STEP 0: Pre-Calculation Summary

Formula Used

Length of Opening = Runoff Quantity/(0.7*(Depression in Curb Inlet+Depth of Flow at Inlet)^(3/2))
L_o = Q_ro/(0.7*(a+y)^(3/2))
This formula uses 4 Variables

Variables Used

Length of Opening - (Measured in Meter) - The Length of Opening refers to the dimension of the structure that allows water to pass through.
Runoff Quantity - (Measured in Cubic Meter per Second) - The Runoff Quantity refers to the amount of water that storms bring to the earth.
Depression in Curb Inlet - (Measured in Meter) - The Depression in Curb Inlet refers to the height of depression at the curb achieved from the steeper grade of the gutter cross slope relative to the roadway cross-slope.
Depth of Flow at Inlet - (Measured in Meter) - The Depth of Flow at Inlet refers to the depth of water in a channel or conduit at the point where water enters a structure, such as a culvert, intake structure, or storm water inlet.

STEP 1: Convert Input(s) to Base Unit

Runoff Quantity: 329 Cubic Foot per Second --> 9.3162425288798 Cubic Meter per Second (Check conversion here)
Depression in Curb Inlet: 4 Foot --> 1.21920000000488 Meter (Check conversion here)
Depth of Flow at Inlet: 7.117 Foot --> 2.16926160000868 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L_o = Q_ro/(0.7*(a+y)^(3/2)) --> 9.3162425288798/(0.7*(1.21920000000488+2.16926160000868)^(3/2))

Evaluating ... ...

L_o = 2.13372719983356

STEP 3: Convert Result to Output's Unit

2.13372719983356 Meter -->7.0004173222606 Foot (Check conversion here)

FINAL ANSWER

7.0004173222606 ≈ 7.000417 Foot <-- Length of Opening
