West European Confederation of Maritime Technology Societies

Is used in psychrometry and is the temperature recorded by a thermometer whose bulb has been covered with a wetted wick and whirled on a sling psychrometer. Taken with the dry bulb, it permits determination of relative humidity of the atmosphere.

Is any gas or gas mixture in which one or more of the constituents is at its saturated vapor pressure. The constituent at saturation pressure may or may not be water vapor.

Is one which 1) handles a small constant flow of liquid with the gas; 2) utilizes evaporative (injection) cooling; or 3) circulates a liquid for sealing and/or cooling. The last may or may not be evaporative cooling.

Difference between the temperatures of the dry-bulb and the wet-bulb thermometers of a psychrometer.

The lowest temperature that can be obtained on a wet-bulb thermometer in any given sample of air. Obtained by evaporation of water (or ice) from the muslin wick. Used in computing dew point and relative humidity.

A thermometer with a muslin-covered bulb which is moistened. used to measure wet-bulb temperature.

A condition in which the interfacial tension between a liquid and a solid is such that the contact angle is 0

A substance that reduces the surface tension of a liquid, thereby causing it to spread more readily on a solid surface.

Charge assessed by a pier or dock owner against freight handled over the pier or dock or against a steamship company using the pier or dock.

Waste Heat Boiler Survey

The process of transmitting electricity over one or more separately owned electric transmission and distribution systems. (See Wholesale and Retail Wheeling.)
