Inlet Capacity for Flow Depth Solution

STEP 0: Pre-Calculation Summary
Formula Used
Water Flow = 3*Perimeter of Grate Opening*Depth of Flow at Inlet^(3/2)
Qw = 3*P*y^(3/2)
This formula uses 3 Variables
Variables Used
Water Flow - (Measured in Cubic Meter per Second) - The Water Flow refers to the movement of water through various natural or engineered systems.
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.
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
Perimeter of Grate Opening: 5 Foot --> 1.5240000000061 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
Qw = 3*P*y^(3/2) --> 3*1.5240000000061*2.16926160000868^(3/2)
Evaluating ... ...
Qw = 14.6074401125476
STEP 3: Convert Result to Output's Unit
14.6074401125476 Cubic Meter per Second --> No Conversion Required
FINAL ANSWER
14.6074401125476 14.60744 Cubic Meter per Second <-- Water Flow
(Calculation completed in 00.004 seconds)

What is an Inlet Structure?

Inlet structures are built to control the amount of water flowing into the pond at all times. An inlet structure may be built for a pond supplied through a feeder canal, for example by diverted stream water, a spring outside the pond, a well or a pumped water supply.

How to Calculate Inlet Capacity for Flow Depth?

Inlet Capacity for Flow Depth calculator uses Water Flow = 3*Perimeter of Grate Opening*Depth of Flow at Inlet^(3/2) to calculate the Water Flow, The Inlet Capacity for Flow Depth up to 4.8in is defined as the capacity of the structures built to control the flow of water known as inlets when flow depth is up to 4.8 inches. Water Flow is denoted by Qw symbol.

How to calculate Inlet Capacity for Flow Depth using this online calculator? To use this online calculator for Inlet Capacity for Flow Depth, enter Perimeter of Grate Opening (P) & Depth of Flow at Inlet (y) and hit the calculate button. Here is how the Inlet Capacity for Flow Depth calculation can be explained with given input values -> 1.857965 = 3*1.5240000000061*2.16926160000868^(3/2).

FAQ

What is Inlet Capacity for Flow Depth?
The Inlet Capacity for Flow Depth up to 4.8in is defined as the capacity of the structures built to control the flow of water known as inlets when flow depth is up to 4.8 inches and is represented as Qw = 3*P*y^(3/2) or Water Flow = 3*Perimeter of Grate Opening*Depth of Flow at Inlet^(3/2). 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 & 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.
How to calculate Inlet Capacity for Flow Depth?
