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/(3*y^(3/2))
This formula uses 3 Variables

Variables Used

Perimeter of grate opening - (Measured in Meter) - Perimeter of grate opening is the length of the circumference of grate opening over which water may flow.
Water Flow - (Measured in Cubic Meter per Second) - Water Flow is rate of flow of water.
Depth of flow at Inlet - (Measured in Meter) - Depth of Flow at Inlet is the flow length at the inlet.

STEP 1: Convert Input(s) to Base Unit

Water Flow: 1.8 Cubic Meter per Second --> 1.8 Cubic Meter per Second No Conversion Required
Depth of flow at Inlet: 1.8 Foot --> 0.548640000002195 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P = Q/(3*y^(3/2)) --> 1.8/(3*0.548640000002195^(3/2))

Evaluating ... ...

P = 1.47645443506773

STEP 3: Convert Result to Output's Unit

1.47645443506773 Meter -->4.84401061371988 Foot (Check conversion here)

FINAL ANSWER

4.84401061371988 ≈ 4.844011 Foot <-- Perimeter of grate opening

(Calculation completed in 00.007 seconds)

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)

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

Perimeter of grate opening = Water Flow/(3*Depth of flow at Inlet^(3/2))
P = Q/(3*y^(3/2))

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.
