Depression in Curb Inlet given Runoff Quantity with Full Gutter flow Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

Depression in Curb Inlet - (Measured in Meter) - Depression in Curb Inlet is the height of depression at the curb achieved from the steeper grade of the gutter cross slope relative to the roadway cross-slope.
Runoff Quantity - (Measured in Cubic Meter per Second) - Runoff Quantity is the amount of water that storms bring to the earth.
Length of Opening - (Measured in Meter) - Length of Opening refers to the dimension of the structure that allows water to pass through.
Depth of Flow at Inlet - (Measured in Meter) - 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)
Length of Opening: 7 Foot --> 2.13360000000853 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

a = ((Q_ro/(0.7*L_o))^(2/3))-y --> ((9.3162425288798/(0.7*2.13360000000853))^(2/3))-2.16926160000868

Evaluating ... ...

a = 1.2193346729958

STEP 3: Convert Result to Output's Unit

1.2193346729958 Meter -->4.00044184052139 Foot (Check conversion here)

FINAL ANSWER

4.00044184052139 ≈ 4.000442 Foot <-- Depression in Curb Inlet

Depth of Flow given Inlet Capacity for Flow Depth more than 1ft 5in

Go Depth = ((Inlet Capacity/(0.6*Area of Opening))^2)*(1/(2*Acceleration Due To Gravity in Environment))

Depression in Curb Inlet given Runoff Quantity with Full Gutter flow

Go Depression in Curb Inlet = ((Runoff Quantity/(0.7*Length of Opening))^(2/3))-Depth of Flow at Inlet

Depth of Flow at Inlet given Runoff Quantity with Full Gutter Flow

Go Depth of Flow at Inlet = ((Runoff Quantity/(0.7*Length of Opening))^(2/3))-Depression in Curb Inlet

Area of Opening given Inlet Capacity for Flow Depth more than 1ft 5in

Go Area of Opening = Inlet Capacity/(0.6*(2*Acceleration Due To Gravity in Environment*Depth)^(1/2))

Length of Opening given Runoff Quantity with Full Gutter Flow

Go Length of Opening = Runoff Quantity/(0.7*(Depression in Curb Inlet+Depth of Flow at Inlet)^(3/2))

Inlet Capacity for Flow Depth more than 1ft 5in

Go Inlet Capacity = 0.6*Area of Opening*((2*Acceleration Due To Gravity in Environment*Depth)^(1/2))

Runoff Quantity with Full Gutter Flow

Go Runoff Quantity = 0.7*Length of Opening*(Depression in Curb Inlet+Depth of Flow at Inlet)^(3/2)

Depth of Flow at Inlet given Inlet Capacity for Flow Depth up to 4.8in

Go Depth of Flow at Inlet = (Water Flow/(3*Perimeter of Grate Opening))^(2/3)

Perimeter when Inlet Capacity for Flow Depth is up to 4.8 inches

Go Perimeter of Grate Opening = Water Flow/(3*Depth of Flow at Inlet^(3/2))

Inlet Capacity for Flow Depth

Go Water Flow = 3*Perimeter of Grate Opening*Depth of Flow at Inlet^(3/2)

Depression in Curb Inlet given Runoff Quantity with Full Gutter flow Formula

Depression in Curb Inlet = ((Runoff Quantity/(0.7*Length of Opening))^(2/3))-Depth of Flow at Inlet
a = ((Q_ro/(0.7*L_o))^(2/3))-y

What is a Curb Inlet?

Curb Inlets are used to assist in storm water drainage of the street surface area. The Curb Inlet is usually a below ground box structure with a vertical opening at the street level.
