### How to determine if mass transfer convection is natural or forced?

The Richardson number $\mathrm{Ri} = \frac{\mathrm{Gr}}{\mathrm{Re}^2} = \frac{\text{buoyancy term}}{\text{flow gradient term}}$ (1) can be used to determine if forced or natural convenction dominate ...

### Can I neglect kinetic energy when modeling convective heat transfer for viscous, low mach airflow? Why or why not?

You should be fine to neglect kinetic energy from a thermal perspective. The kinetic energy per unit volume will be $1/2 \rho u^2$, which is about 2800 $J/m^3$ for your conditions. Given that the ...
