Critical Velocity given Maximum Discharge Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
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 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

Peak Discharge: 39.77 Cubic Meter per Second --> 39.77 Cubic Meter per Second No Conversion Required
Width of Throat: 3 Meter --> 3 Meter No Conversion Required
Critical Depth: 2.62 Meter --> 2.62 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_c = (Q_p/(W_t*d_c)) --> (39.77/(3*2.62))

Evaluating ... ...

V_c = 5.05979643765903

STEP 3: Convert Result to Output's Unit

5.05979643765903 Meter per Second --> No Conversion Required

FINAL ANSWER

5.05979643765903 ≈ 5.059796 Meter per Second <-- Critical Velocity

What is Critical Velocity?

The velocity at which flow transitions from being subcritical to supercritical. In open channel flow, critical velocity occurs when the flow's kinetic energy is equal to the potential energy. It's a point where the flow is neither too fast nor too slow, and it determines the efficiency and behavior of the channel.

How to Calculate Critical Velocity given Maximum Discharge?

Critical Velocity given Maximum Discharge calculator uses Critical Velocity = (Peak Discharge/(Width of Throat*Critical Depth)) to calculate the Critical Velocity, The Critical Velocity given Maximum Discharge formula is defined as the velocity at which flow transitions from being subcritical to supercritical. In open channel flow, critical velocity occurs when the flow's kinetic energy is equal to the potential energy, considering the maximum discharge flow. Critical Velocity is denoted by V_c symbol.

How to calculate Critical Velocity given Maximum Discharge using this online calculator? To use this online calculator for Critical Velocity given Maximum Discharge, enter Peak Discharge (Q_p), Width of Throat (W_t) & Critical Depth (d_c) and hit the calculate button. Here is how the Critical Velocity given Maximum Discharge calculation can be explained with given input values -> 0.508906 = (39.77/(3*2.62)).

FAQ

What is Critical Velocity given Maximum Discharge?

The Critical Velocity given Maximum Discharge formula is defined as the velocity at which flow transitions from being subcritical to supercritical. In open channel flow, critical velocity occurs when the flow's kinetic energy is equal to the potential energy, considering the maximum discharge flow and is represented as V_c = (Q_p/(W_t*d_c)) or Critical Velocity = (Peak Discharge/(Width of Throat*Critical Depth)). Peak Discharge is the maximum volume flow rate passing a particular location during an event, Width of Throat is the narrowest section of a conduit or channel, such as in a venturi meter or flume & 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.

How to calculate Critical Velocity given Maximum Discharge?

The Critical Velocity given Maximum Discharge formula is defined as the velocity at which flow transitions from being subcritical to supercritical. In open channel flow, critical velocity occurs when the flow's kinetic energy is equal to the potential energy, considering the maximum discharge flow is calculated using Critical Velocity = (Peak Discharge/(Width of Throat*Critical Depth)). To calculate Critical Velocity given Maximum Discharge, you need Peak Discharge (Q_p), Width of Throat (W_t) & Critical Depth (d_c).
