Wind effect
Air currents, in the vent stack of a drainage system could cause the water seal in a trap to be lost or can change the water level in a drain trap.
Wind energy efficiency
Energy available from the movement of the wind across a landscape caused by the heating of the atmosphere, earth, and oceans by the sun.
Wind energy efficiency conversion system (wecs) or device
An apparatus for converting the energy available in the wind to mechanical energy that can be used to power machinery (grain mills, water pumps) and to operate an electrical generator.
Wind load
The forces superimposed on a building or structure by the movement of an air mass at a specified velocity.
Wind load or force
Effect caused to a structure, by the force of the wind blowing on it, which is considered during the design phase.
Wind power plant
A group of wind turbines interconnected to a common utility system through a system of transformers, distribution lines, and (usually) one substation. Operation, control, and maintenance functions are often centralized through a network of computerized monitoring systems, supplemented by visual inspection. This is a term commonly used in the United States. In Europe, it is called a generating station.
Wind resource assessment
The process of characterizing the wind resource, and its energy potential, for a specific site or geographical area.
Wind rose
A diagram that indicates the average percentage of time that the wind blows from different directions, on a monthly or annual basis.
