What is the meaning of wet leg & where is it used?
Answer:
A process used to determine the differential pressure
present within a liquid-filled space.
The formula for determining the differential pressure
within a wet leg design is: d/p = h (SG)
Where: d/p = differential pressure, h = height of liquid
present, and SG = specific gravity
When the process vapors condense at normal ambient
temperatures or are corrosive, this reference leg can be
filled to form a wet leg. If the process condensate is
corrosive, unstable, or undesirable to use to fill the wet
leg, this reference leg can be filled with an inert liquid.
