Measured Unsteady Flow Solution

Follow our step by step solution on how to calculate Measured Unsteady Flow?

FIRST Step Consider the formula

Q M = Q n \cdot \sqrt{1 + (\frac{1}{v W \cdot S o}) \cdot dh /dt}

Next Step Substitute values of Variables

∴

Q M = 12m³/s \cdot \sqrt{1 + (\frac{1}{50m/s \cdot 0.1}) \cdot 2.2}

Next Step Prepare to Evaluate

∴

Q M = 12 \cdot \sqrt{1 + (\frac{1}{50 \cdot 0.1}) \cdot 2.2}

LAST Step Evaluate

∴

Q M = 14.4m³/s

How to Evaluate Measured Unsteady Flow?

Measured Unsteady Flow evaluator uses Measured Unsteady Flow = Normal Discharge*sqrt(1+(1/(Velocity of Flood Wave*Channel Slope))*Rate of Change of Stage) to evaluate the Measured Unsteady Flow, The Measured Unsteady Flow formula is defined as that at the same stage, more discharge passes through the river during rising stages than in falling ones. Measured Unsteady Flow is denoted by Q_M symbol.

How to evaluate Measured Unsteady Flow using this online evaluator? To use this online evaluator for Measured Unsteady Flow, enter Normal Discharge (Q_n), Velocity of Flood Wave (v_W), Channel Slope (S_o) & Rate of Change of Stage (dh_/dt) and hit the calculate button.

FAQs on Measured Unsteady Flow

What is the formula to find Measured Unsteady Flow?

The formula of Measured Unsteady Flow is expressed as Measured Unsteady Flow = Normal Discharge*sqrt(1+(1/(Velocity of Flood Wave*Channel Slope))*Rate of Change of Stage). Here is an example- 14.4 = 12*sqrt(1+(1/(50*0.1))*2.2).

How to calculate Measured Unsteady Flow?

With Normal Discharge (Q_n), Velocity of Flood Wave (v_W), Channel Slope (S_o) & Rate of Change of Stage (dh_/dt) we can find Measured Unsteady Flow using the formula - Measured Unsteady Flow = Normal Discharge*sqrt(1+(1/(Velocity of Flood Wave*Channel Slope))*Rate of Change of Stage). This formula also uses Square Root (sqrt) function(s).

Can the Measured Unsteady Flow be negative?

No, the Measured Unsteady Flow, measured in Volumetric Flow Rate cannot be negative.

Which unit is used to measure Measured Unsteady Flow?

Measured Unsteady Flow is usually measured using the Cubic Meter per Second[m³/s] for Volumetric Flow Rate. Cubic Meter per Day[m³/s], Cubic Meter per Hour[m³/s], Cubic Meter per Minute[m³/s] are the few other units in which Measured Unsteady Flow can be measured.
