Vapor pressure is the result of a fluid’s vaporization and is a 14. Define vaporization.
measured pressure in closed systems. Vaporization is the
transformation of a substance from a liquid state to a gas state
(e.g., water to steam). The transformation occurs at a specific
temperature for each liquid. For example, water turns to steam
(boils) at 212 °F (100 °C). Vapor pressure is most commonly
measured in closed tank DP level applications, whereby the
vapor pressure is the low side transmitter measurement.
