The diameter of the inlet nozzle is the function of the feed flow rate & the pressure. The criterion for nozzle sizing is that the momentum of the feed shall not exceed prescribed levels. The maximum allowable inlet momentum can be increased by fitting inlet devices. The vessel requires an inlet nozzle at each end, terminated by an elbow or a half-open pipe, and one vapor outlet nozzle at the center of the vessel. This setup reduces the required cross-sectional vapor area by 50%. However, with small low-pressure vessels, the savings from the smaller diameter may be offset by the cost of the vertical demisters and the extra inlet.
