Pressure and Density (Isentropic Relationships)

Pressure and Density Equation

$$ \frac{p_2}{p_1} = \left( \frac{\rho_2}{\rho_1} \right)^\gamma $$ where:

p₁ = Pressure at point 1 (Pa)

p₂ = Pressure at point 2 (Pa)

ρ₁ = Density at point 1 (kg/m³)

ρ₂ = Density at point 2 (kg/m³)

γ = Ratio of Specific Heats (Dimensionless)
