Discharge Passing through Parshall Flume Solution

STEP 0: Pre-Calculation Summary
Formula Used
Environmental Discharge = (2.264*Width of throat*(Depth of Flow)^(3/2))
Qe = (2.264*Wt*(df)^(3/2))
This formula uses 3 Variables
Variables Used
Environmental Discharge - (Measured in Cubic Meter per Second) - Environmental Discharge is the rate of flow of a liquid.
Width of throat - (Measured in Meter) - Width of throat of the parshall flume is denoted by W symbol.
Depth of Flow - (Measured in Meter) - Depth of Flow is the distance from the top or surface of the flow to the bottom of a channel or other waterway or Depth of Flow at the Vertical while measuring Sound Weights.
STEP 1: Convert Input(s) to Base Unit
Width of throat: 3 Meter --> 3 Meter No Conversion Required
Depth of Flow: 3.3 Meter --> 3.3 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Qe = (2.264*Wt*(df)^(3/2)) --> (2.264*3*(3.3)^(3/2))
Evaluating ... ...
Qe = 40.7163263859597
STEP 3: Convert Result to Output's Unit
40.7163263859597 Cubic Meter per Second --> No Conversion Required
FINAL ANSWER
40.7163263859597 40.71633 Cubic Meter per Second <-- Environmental Discharge
(Calculation completed in 00.004 seconds)

8 Parshall Flume Calculators

Depth of Parshall Flume given Discharge
Go Depth = (Environmental Discharge/Integration Constant)^(1/Discharge coefficient)
Depth of Parshall Flume given Width
Go Depth = (Integration Constant*Width)^(1/(Discharge coefficient-1))
Width of Parshall Flume given Depth
Go Width = ((Depth)^(Discharge coefficient-1))/Integration Constant
Depth of Flow in Upstream Leg of Flume at One Third Point given Discharge
Go Depth of Flow = (Environmental Discharge/(2.264*Width of throat))^(2/3)
Discharge Passing through Parshall Flume
Go Environmental Discharge = (2.264*Width of throat*(Depth of Flow)^(3/2))
Width of Throat given Discharge
Go Width of throat = Environmental Discharge/(2.264*(Depth of Flow)^(3/2))
Width of Parshall Flume given Depth of Parshall Flume
Go Width = sqrt(Depth/Integration Constant)
Depth of Parshall Flume
Go Depth = Integration Constant*Width*Width

Discharge Passing through Parshall Flume Formula

Environmental Discharge = (2.264*Width of throat*(Depth of Flow)^(3/2))
Qe = (2.264*Wt*(df)^(3/2))

What is normal depth ?

Normal depth is the depth of flow in a channel or culvert when the slope of the water surface and channel bottom is the same and the water depth remains constant.
