: For problems where the surface temperature is unknown, the manual demonstrates iterative approaches to find the correct Rayleigh and Nusselt numbers.

), this value determines whether the fluid flow is laminar or turbulent. : For problems where the surface temperature is

In free convection, the fluid motion is caused by density differences in the fluid due to temperature variations. The fluid rises when it is heated and sinks when it is cooled. Gr = (ρ^2 * g * β *

Gr = (ρ^2 * g * β * (T_s - T_∞) * L^3) / μ^2

Q=hAs(Ts−T∞)cap Q equals h cap A sub s open paren cap T sub s minus cap T sub infinity end-sub close paren

Assuming the tube to be a vertical tube, the characteristic length is:
