Depth of Flow at Inlet when Runoff Quantity with Full Gutter Flow is Giiven Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

Depth of flow at Inlet - (Measured in Meter) - Depth of Flow at Inlet is the flow length at the inlet.
Quantity of Runoff - (Measured in Cubic Meter per Second) - Quantity of Runoff is the amount of water that storms bring to the earth.
Length of Opening - (Measured in Meter) - Length of Opening is the length of the opening in ground.
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.

STEP 1: Convert Input(s) to Base Unit

Quantity of Runoff: 125 Cubic Foot per Second --> 3.53960582404248 Cubic Meter per Second (Check conversion here)
Length of Opening: 7 Foot --> 2.13360000000853 Meter (Check conversion here)
Depression in Curb Inlet: 4 Foot --> 1.21920000000488 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

y = ((Q_R/(0.7*L_o))^(2/3))-a --> ((3.53960582404248/(0.7*2.13360000000853))^(2/3))-1.21920000000488

Evaluating ... ...

y = 0.558380342217461

STEP 3: Convert Result to Output's Unit

0.558380342217461 Meter -->1.8319565033308 Foot (Check conversion here)

FINAL ANSWER

1.8319565033308 ≈ 1.831957 Foot <-- Depth of flow at Inlet

Depth of Flow at Inlet when Runoff Quantity with Full Gutter Flow is Giiven

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

Depression in Curb Inlet given Runoff Quantity with Full Gutter flow

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

Length of Opening given Runoff Quantity with Full Gutter Flow

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

Runoff Quantity with Full Gutter Flow

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

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

Go Depth = ((Inlet Capacity/(0.6*Area))^2)*(1/(2*Acceleration due to Gravity))

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

Go Area = Inlet Capacity/(0.6*(2*Acceleration due to Gravity*Depth)^(1/2))

Inlet Capacity for Flow Depth more than 1ft 5in

Go Inlet Capacity = 0.6*Area*((2*Acceleration due to Gravity*Depth)^(1/2))

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)

Depth of Flow at Inlet when Runoff Quantity with Full Gutter Flow is Giiven Formula

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

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.
