I am confused about the usage and meaning of, Calculated BC.
in many OF Tutorials it has been used in 0/nut file for inlet and outlet.
Can anyone please throw some light on it.

calculated means, that the property you are referring to is already fully defined by the other boundary conditions and properties you defined in the constant folder.
For example nu_t (or mu_t) is defined via k and epsilon by
nu_t= C * k^2/epsilon
So OpenFOAM can calculate the boundary conditions for nu_t via the ones you gave it for k and epsilon. You only specify the wall-function for nu_t.

It means the values are calculated from the turbulence model and the values for k and epsilon (or omega) and not prescribed.
