Article – March 26, By LarsonElectronics. Wind speed and frequency can affect the stable and reliable nature of industrial light towers, antennas and mounted fixtures in outdoor locations. Such conditions place stress on elevated structures. EPA and Lighting Systems. Understanding EPA and its benefits for lighting manufacturers and industrial operators is equally as important as the calculation itself.
By finding the EPA, individuals can determine the strength of the pole holding up the lighting system, during exposure to strong winds or powerful storms. Furthermore, lighting manufacturers may use the coefficient to analyze the amount of force a lamp will have on a mast, pole or mounting bracket, when exposed to certain, wind-related conditions.
Generally speaking, it is possible to calculate for the EPA by taking the projected area and relevant drag coefficient variable: The FPA is typically expressed in square feet or ft2. It takes the measurement of the front cross sectional area of the fixture maximumalong with the mount. This is the side or surface that is exposed to wind. In this equation, the drag coefficient refers to resistance arising from the object or shape of the surface in relation to air movement.
Examples of existing drag coefficient variables include: The drag coefficient variable is considered to be a dimensionless constant, which can be calculated using the following formula: Plug in the variables, based on the EPA formula above: Need industrial light towers?
