Maximum Discharge given Width of Throat Solution

STEP 0: Pre-Calculation Summary

Formula Used

Peak Discharge = Width of Throat*Critical Velocity*Critical Depth
Q_p = W_t*V_c*d_c
This formula uses 4 Variables

Variables Used

Peak Discharge - (Measured in Cubic Meter per Second) - Peak Discharge is the maximum volume flow rate passing a particular location during an event.
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.
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.
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.

STEP 1: Convert Input(s) to Base Unit

Width of Throat: 3 Meter --> 3 Meter No Conversion Required
Critical Velocity: 5.06 Meter per Second --> 5.06 Meter per Second No Conversion Required
Critical Depth: 2.62 Meter --> 2.62 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_p = W_t*V_c*d_c --> 3*5.06*2.62

Evaluating ... ...

Q_p = 39.7716

STEP 3: Convert Result to Output's Unit

39.7716 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

39.7716 Cubic Meter per Second <-- Peak Discharge

< Discharge in Channel Calculators

Discharge for Rectangular Channel Section

Go Environmental Discharge = Area of Cross Section*(Hydraulic Radius^(2/3))*(Slope of Bed^(1/2))/Manning’s Roughness Coefficient

Discharge Coefficient with known Discharge

Go Discharge Coefficient = -log(Theoretical Discharge/Integration Constant,Depth)

Discharge Passing through Parshall Flume given Discharge Coefficient

Go Environmental Discharge = Integration Constant*(Depth)^(Discharge Coefficient)

Discharge through Control Section

Go Environmental Discharge = Width of Throat*Critical Velocity*Critical Depth

Maximum Discharge given Width of Throat Formula

Peak Discharge = Width of Throat*Critical Velocity*Critical Depth
Q_p = W_t*V_c*d_c

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.

How to Calculate Maximum Discharge given Width of Throat?

Maximum Discharge given Width of Throat calculator uses Peak Discharge = Width of Throat*Critical Velocity*Critical Depth to calculate the Peak Discharge, The Maximum Discharge given Width of Throat formula is defined as the maximum amount of fluid passing a section of a stream in unit time. Peak Discharge is denoted by Q_p symbol.

How to calculate Maximum Discharge given Width of Throat using this online calculator? To use this online calculator for Maximum Discharge given Width of Throat, enter Width of Throat (W_t), Critical Velocity (V_c) & Critical Depth (d_c) and hit the calculate button. Here is how the Maximum Discharge given Width of Throat calculation can be explained with given input values -> 39.7716 = 3*5.06*2.62.
