heat transfer in mechanica

[tonz1984]

Hello

A little help with Pro Mechanica Thermal application is required, any help is really appreciated.

When calculating the Grashof number to get 'h' values for the boundary conditions, I input an estimated surface temperature(Ts), and an estimated fluid temperature (Tf).

Is this estimated fluid temperature(Tf) the same value as used for the 'bulk temperature'(Tb) when you input the 'h' value into Pro M?

thanks
