Pipe Diameter Sizing Calculator

Size pipe diameter for given flow rate and velocity or pressure drop constraints. Recommended velocities: water 1-3 m/s, gas 5-15 m/s, steam 20-40 m/s. NPS and DN sizing with schedule selection.

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.
