I know the answer to this question depends on factors such as insulation and mass flow rate, but I am just looking for a practical answer. When steam expands through a PRV from let's say 100 psig to 50 psig, it becomes superheated due to constant enthalpy. My question is, how long does this superheat last? In other words, at what point has the steam cooled down to saturation at the lower pressure? Obviously that depends on pipe insulation, etc., but has anyone ever measured it? I'm just looking for a practical understanding. Is the superheat gone a few feet downstream of the PRV, or could the steam still be superheated a considerable distance away when that steam finally hits a device?
