In a two-phase release scenario, which phase is expected to be released as a liquid stream?

• A. Vapor plume
• B. Solid discharge
• C. Liquid stream
• D. Aerosol

Answer: (C)

In a two-phase release, the material separates into a liquid portion and a vapor portion. The liquid portion exits the source as a liquid stream, maintaining its liquid state as it flows away, forming a continuous jet or stream. The vapor portion expands into the surrounding air as a vapor plume, which is the gaseous phase. An aerosol would be fine droplets suspended in air, which can occur under some conditions, but the plain liquid stream specifically refers to the liquid phase. Solid discharge would involve solids, not a liquid phase, so it doesn’t fit the scenario.
