Orifice Flow Calculator

Calculate discharge through orifice: Q = Cd·A·√(2gh). Discharge coefficients: sharp-edged Cd = 0.61, rounded Cd = 0.98, re-entrant Cd = 0.50. Vena contracta and flow measurement applications.

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.
