Open Channel Flow Calculator

Calculate discharge, velocity, and normal depth in open channels using Manning equation. Critical depth y_c = (q²/g)^(1/3). Specific energy E = y + V²/(2g). Most efficient section design.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)
⚙ Mechanical Note: Results are based on standard textbook formulas and ISO/AASHTO references. Always verify critical designs with applicable codes (ISO 898, AASHTO 1993, AISC, Eurocode 3) and a qualified engineer.

How It Works

Calculate discharge, velocity, and normal depth in open channels using Manning equation. Critical depth y_c = (q²/g)^(1/3). Specific energy E = y + V²/(2g). Most efficient section design

Each component has a specific meaning:

  • Manning equation — The manning equation recorded for the patient or scenario being assessed.

Note: Interpret the open channel flow result against the clinical thresholds and context described above.

How to Use

Enter the Manning equation for the patient or scenario you are assessing. Calculate discharge, velocity, and normal depth in open channels using Manning equation. Critical depth y_c = (q²/g)^(1/3). Specific energy E = y + V²/(2g). Most efficient section design. Use the open channel flow result to inform your clinical assessment.
