Discharge given Critical Depth Solution

STEP 0: Pre-Calculation Summary

Formula Used

Environmental Discharge = sqrt(((Critical Depth)^3)*Acceleration due to Gravity*(Width of Throat)^2)
Q_e = sqrt(((d_c)^3)*g*(W_t)^2)
This formula uses 1 Functions, 4 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Environmental Discharge - (Measured in Cubic Meter per Second) - Environmental Discharge is the rate of flow of a liquid.
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.
Acceleration due to Gravity - (Measured in Meter per Square Second) - Acceleration due to Gravity is a fundamental physical constant that represents the acceleration of an object due to the force of gravity exerted by the Earth.
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.

STEP 1: Convert Input(s) to Base Unit

Critical Depth: 2.62 Meter --> 2.62 Meter No Conversion Required
Acceleration due to Gravity: 9.8 Meter per Square Second --> 9.8 Meter per Square Second No Conversion Required
Width of Throat: 3 Meter --> 3 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_e = sqrt(((d_c)^3)*g*(W_t)^2) --> sqrt(((2.62)^3)*9.8*(3)^2)

Evaluating ... ...

Q_e = 39.8277919247352

STEP 3: Convert Result to Output's Unit

39.8277919247352 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

39.8277919247352 ≈ 39.82779 Cubic Meter per Second <-- Environmental Discharge

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 Discharge given Critical Depth?

Discharge given Critical Depth calculator uses Environmental Discharge = sqrt(((Critical Depth)^3)*Acceleration due to Gravity*(Width of Throat)^2) to calculate the Environmental Discharge, The Discharge given Critical Depth formula is defined as the volume of fluid (usually water) flowing through a channel per unit time, considering critical depth. Environmental Discharge is denoted by Q_e symbol.

How to calculate Discharge given Critical Depth using this online calculator? To use this online calculator for Discharge given Critical Depth, enter Critical Depth (d_c), Acceleration due to Gravity (g) & Width of Throat (W_t) and hit the calculate button.
