Reynolds Number Calculator

Calculate the Reynolds number Re = ρVD/μ = VD/ν to determine flow regime. Laminar: Re < 2300, Transitional: 2300–4000, Turbulent: Re > 4000. Critical for pipe and channel 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.
