CRITICAL PRESSURE AND CRITICAL TEMPERATURE

That point at which the difference between the liquid and vapor states for water completely disappears.

DOWNCOMER

A tube or pipe in a boiler or waterwall circulating system through which fluid flows downward between headers.

EJECTOR

A device which utilizes the kinetic energy in a jet of water or other fluid to remove a fluid or fluent material from tanks or hoppers.

ENTHALPY

A thermal property of a fluid which is a function of state and is defined as the sum of stored mechanical potential energy and internal energy. It is generally expressed in Btu per pound of fluid (joules per kilogram).

GLOBE VALVE

A stop valve using the round-disk-and-seat principle. Used where the fluid controlled is comparatively clean.

MANIFOLD

A pipe or header for collecting a fluid from, or the distributing of a fluid to a number of pipes or tubes.

NOZZLE

A short flanged or welded neck connection on a drum or shell for the outlet or inlet of fluids; also a protecting spout for the outlet or inlet of fluids; also a projecting spout through which fluid flows.

PASS

A confined passageway, containing heating surface, through which fluid flows essentially one direction.

VISCOSITY

Measure of the internal friction of a fluid or its resistance to flow.

CONVECTION

The transfer of heat or mass by large-scale fluid movements. When the process occurs, due to density and temperature differences, it is termed natural convection. When the process occurs due to external devices (such as fans), it is termed forced convection.
