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

STEP 0: Pre-Calculation Summary

Formula Used

Perimeter of Grate Opening = Water Flow/(3*Depth of Flow at Inlet^(3/2))
P = Q_w/(3*y^(3/2))
This formula uses 3 Variables

Variables Used

Perimeter of Grate Opening - (Measured in Meter) - The Perimeter of Grate Opening refers to the boundary or outline of the opening in a grate that allows water to enter a storm water collection or drainage system.
Water Flow - (Measured in Cubic Meter per Second) - The Water Flow refers to the movement of water through various natural or engineered systems.
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

Water Flow: 14.61 Cubic Meter per Second --> 14.61 Cubic Meter per Second No Conversion Required
Depth of Flow at Inlet: 7.117 Foot --> 2.16926160000868 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P = Q_w/(3*y^(3/2)) --> 14.61/(3*2.16926160000868^(3/2))

Evaluating ... ...

P = 1.52426707407571

STEP 3: Convert Result to Output's Unit

1.52426707407571 Meter -->5.0008762272625 Foot (Check conversion here)

FINAL ANSWER

5.0008762272625 ≈ 5.000876 Foot <-- Perimeter of Grate Opening

(Calculation completed in 00.020 seconds)
