Width of Throat given Maximum Discharge Solution

STEP 0: Pre-Calculation Summary

Formula Used

Width of throat = (Peak Discharge/(Critical Depth*Critical Velocity))
W_t = (Q_p/(CD*V_c))
This formula uses 4 Variables

Variables Used

Width of throat - (Measured in Meter) - Width of throat of the parshall flume is denoted by W symbol.
Peak Discharge - (Measured in Cubic Meter per Second) - Peak Discharge is the maximum volume flow rate passing a particular location during an event.
Critical Depth - (Measured in Meter) - Critical depth occurs when the flow in a channel has a minimum specific energy. Specific energy refers to the sum of the depth of flow and the velocity head.
Critical Velocity - (Measured in Meter per Second) - The Critical velocity is the greatest velocity with which a fluid can flow through a given conduit without becoming turbulent.

STEP 1: Convert Input(s) to Base Unit

Peak Discharge: 4 Cubic Meter per Second --> 4 Cubic Meter per Second No Conversion Required
Critical Depth: 4 Meter --> 4 Meter No Conversion Required
Critical Velocity: 15 Meter per Second --> 15 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

W_t = (Q_p/(CD*V_c)) --> (4/(4*15))

Evaluating ... ...

W_t = 0.0666666666666667

STEP 3: Convert Result to Output's Unit

0.0666666666666667 Meter --> No Conversion Required

FINAL ANSWER

0.0666666666666667 ≈ 0.066667 Meter <-- Width of throat

What is discharge ?

The amount of fluid passing a section of a stream in unit time is called the discharge. If v is the mean velocity and A is the cross sectional area, the discharge Q is defined by Q = Av which is known as volume flow rate. Discharge is also expressed as mass flow rate and weight flow rate.
