Isentropic Flow Calculator

Calculate relationships between temperature, density, and pressure for isentropic (adiabatic and frictionless) flow of an ideal gas using the fundamental equations of isentropic flow thermodynamics.

Calculator

Inputs

Initial Temperature (T1) (K)

Final Temperature (T2) (K)

Initial Density (ρ1) (kg/m³)

Final Density (ρ2) (kg/m³)

Initial Pressure (p1) (Pa)

Final Pressure (p2) (Pa)

Specific Heat Ratio (κ) (dimensionless)

Specific Volume (v) (m³/kg)

Results

Temperature Ratio (T2/T1)-- dimensionless

Density Ratio (ρ2/ρ1)-- dimensionless

Pressure Ratio (p2/p1)-- dimensionless

Isentropic Temperature-Density Relation: (T2/T1)^(κ/(κ-1))-- dimensionless

Isentropic Density-Pressure Relation: (ρ2/ρ1)^κ-- dimensionless

p·v^κ (Should be constant for isentropic process)-- Pa·(m³/kg)^κ

p·ρ^(-κ) (Should be constant for isentropic process)-- Pa·(kg/m³)^(-κ)
