Flashing liquids escaping through holes and pipes require special consideration because two-phase flow conditions may be present. Several special cases need consideration.17 If the fluid path length of the release is short (through a hole in a thin-walled container), nonequilibrium conditions exist, and the liquid does not have time to flash within the hole the fluid flashes external to the hole. The equations describing incompressible fluid flow through holes apply (see section 4-2). 

Determine the proper relief diameter for the following two-phase flow conditions. Assume in all cases that LID = 0.0. 

Modulating pilot valves shall be exclusively used for two-phase flow conditions. All pilot-operated valves shall be equipped with on-site test connections and equipped with a supply filter with minimum 60 pm element. Pilot-operated valves can be of semi- or full nozzle design.

If, due to pressure drop and temperature rise, the liquid hydrogen is permitted to reach the saturation line at a point preceding the required design length, then a two-phase flow condition will exist which will cause the single-phase flow equations to be invalid. Due to added turbulence, the frictional pressure drop for two-phase flow will tend to be greater than a pressure drop for a singlephase system with equal mass flow rate.
