Orifice Plate Flow Measurement Calculator

Calculate volumetric flow Q = Cd × A × √(2ΔP/ρ(1−β4)) through an orifice plate per ISO 5167. Determine differential pressure range and Cd for given pipe and orifice diameter.

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.
