Isentropic Efficiency Turbine Calculator

Calculate turbine isentropic efficiency η_T = (h₁-h₂)/(h₁-h₂s). Typical steam turbine η_T = 0.85-0.92. Polytropic efficiency for stage analysis. Compressor isentropic efficiency η_C = (h₂s-h₁)/(h₂-h₁).

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.
