WebRadiometry Irradiance E [W/cm 2] At a point of a surface, the radiant energy flux (or power) incident on an element of the surface, divided by the area of the surface. The power P [W] that irradiates a surface area A [cm2] is called the Irradiance E … WebIrradiance definition, incident flux of radiant energy per unit area. See more.
WebFirst, you have to be able to calculate the fluence rate (irradiance) distribution within the UV reactor. This requires a sophisticated computer program. Then you must carry out a volume average of the fluence rate (irradiance) over the entire reactor. The residence time of the air in the reactor is given by: volume/(flow rate). Webthe units W/m 2 for irradiance or fluence rate and J/m for fluence (UV dose) are more commonly used. One mW/cm 2 = 10 W/m and 1 mJ/cm 2 = 10 J/m. The tables Five tables have been prepared covering spores, bacteria, viruses, algae and other microorganisms. These tables – as well as a reference list – are too large for print, but the full ...

WebThe Irradiance (continued) The irradiance (or intensity) is the magnitude of the time average of the Poynting vector: Since the time-dependence of S is given by a cos2, we must take the time average of this function. 22 (,) cos( ) 00 Srt c E B k r t The average of cos2(x) is ½:
WebDose (Fluence), Irradiance and Contact Time - Theory behind the UV-Tube. To inactivate a given microorganism the water must be hit with a certain amount or dose of UV light. Dose, more properly referred to as fluence, is determined by variables associated with the design and operation of the UV disinfection device, as well as the ...
