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*CD))
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 of the parshall flume is denoted by W symbol.
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: 4 Cubic Meter per Second --> 4 Cubic Meter per Second No Conversion Required
Width of throat: 3 Meter --> 3 Meter No Conversion Required
Critical Depth: 4 Meter --> 4 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_c = (Q_p/(W_t*CD)) --> (4/(3*4))

Evaluating ... ...

V_c = 0.333333333333333

STEP 3: Convert Result to Output's Unit

0.333333333333333 Meter per Second --> No Conversion Required

FINAL ANSWER

0.333333333333333 ≈ 0.333333 Meter per Second <-- Critical Velocity
