Critical Depth given Maximum Discharge Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
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.

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 Velocity: 5.06 Meter per Second --> 5.06 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

d_c = (Q_p/(W_t*V_c)) --> (39.77/(3*5.06))

Evaluating ... ...

d_c = 2.61989459815547

STEP 3: Convert Result to Output's Unit

2.61989459815547 Meter --> No Conversion Required

FINAL ANSWER

2.61989459815547 ≈ 2.619895 Meter <-- Critical Depth
