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))
Q_e = (2.264*W_t*(d_f)^(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 is the narrowest section of a conduit or channel, such as in a venturi meter or flume.
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

Q_e = (2.264*W_t*(d_f)^(3/2)) --> (2.264*3*(3.3)^(3/2))

Evaluating ... ...

Q_e = 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
