📊 Fluid Outputs

Density ($\rho$) — kg/m³

Specific Heat ($C_p$) — J/(kg·K)

Thermal Conductivity ($k$) — W/(m·K)

Dynamic Viscosity ($\mu$) — Pa·s

Kinematic Viscosity ($\nu$) — m²/s

Prandtl Number ($Pr$) — dimensionless

Thermal Diffusivity ($\alpha$) — m²/s

Expansion Coeff. ($\beta$) — 1/K

📈 Property Curves vs. Temperature

Interpolation Model:
Calculated using high-precision linear spline interpolation over tabulated database data points sourced from Incropera & DeWitt (Appendix A) and Cengel.

Expansion Coefficient:
• Gas: $\beta = 1/T_K$ (ideal gas law)
• Liquid: numerical derivative $\beta = - \frac{1}{\rho}\frac{\partial\rho}{\partial T}$
