Isentropic Pressure-Temperature (Adiabtic Flow) Calculator

Isentropic Pressure-Temperature Relationship

Isentropic Pressure-Temperature Equation

$$ \frac{p_2}{p_1} = {\left(\frac{T_2}{T_1}\right)}^{\frac{\gamma}{\gamma - 1}} $$ where:

p₁ = Initial pressure (Pa)

p₂ = Final pressure (Pa)

T₁ = Initial Temperature (K)

T₂ = Final Temperature (K)

γ = Ratio of Specific Heats (dimensionless)

Ma = Mach number (dimensionless)
