Limit the pressure drop in the discharge line to 6 psid whenever possible to minimize the adverse effect on unit capacity and efficiency. While a pressure drop of as much as 10 psid is usually permissible, note that a 6-psid pressure drop reduces unit capacity by 0.9 percent and efficiency by 3 percent. To design the discharge line properly,kpa = kilopascals Bar = atmospheres where 1 Bar = 14.5 psig or normal pressure at sea level.
