Isentropic Flow Calculator
Calculate stagnation-to-static ratios for compressible ideal gas flow.
How to Use This Calculator
Enter the ratio of specific heats (γ) and Mach number (M). Common values: air γ≈1.4. The tool returns stagnation-to-static ratios.
Formula
T₀/T = 1 + (γ−1) M² / 2
p₀/p = (T₀/T)^(γ/(γ−1))
ρ₀/ρ = (T₀/T)^(1/(γ−1))
About Isentropic Flow
Isentropic (adiabatic and reversible) compressible flow relates stagnation and static properties via Mach number for ideal gases.
Frequently Asked Questions
What about area–Mach relation?
This tool focuses on property ratios. Area–Mach and mass flow choked relations are not included.
Can γ vary with temperature?
Yes, but this calculator assumes constant γ for simplicity.
