This standard specifies a method to calculate the density of water vapour flow rate for cold pipes, and the total amount of water absorption over time. This calculation method applies only when the water vapour partial pressure difference is perpendicular to the axis of the pipes and the water vapour partial pressure is constant at all points equidistant from the axis of the pipe.
