When performing distillation design, how are the pressure of the top condenser and the pressure drop across the trays entered?

Whether it is a simple calculation or the radftac module, pressure needs to be inputted. How should this pressure be entered? Based on what? New to the chemical industry, thanks for your guidance!
The tower top pressure and the overall tower pressure drop can be set.
The pressure is generally determined based on the corresponding bubble point, to ensure that the material at the top of the tower can be cooled using circulating water at that pressure
