Density: $1 \, \text{kg/m}^3 = 0.0624 \, \text{lb/ft}^3$
Specific Heat: $1 \, \text{kJ/kg K} = 0.2389 \, \text{kcal/(kg °C)} = 0.2389 \, \text{Btu/lb °F}$
Thermal Conductivity: $1 \, \text{W/(m K)} = 0.5779 \, \text{Btu/(ft h °F)}$
Dynamic Viscosity: $1 \, \text{Pa s} = 10 \, \text{Poise (P)} = 1000 \, \text{centipoise (cP)} = 0.1020 \, \text{kp s/m}^2 = 0.6721 \, \text{lb/(ft s)}$

The Prandtl Number (Pr) is a dimensionless number relating momentum and thermal diffusivity, defined as:

Pr = \frac{\mu c_p}{\lambda}

where $\mu$ is dynamic viscosity, $c_p$ is specific heat, and $\lambda$ is thermal conductivity.

The Reynolds Number (Re) for flow in a pipe is:

Re = \frac{\rho v D}{\mu}

where $\rho$ is density, $v$ is velocity, and $D$ is pipe diameter.

The Nusselt Number (Nu) for convective heat transfer often follows correlations of the form:

Nu = C \cdot Re^m \cdot Pr^n
