45、 has been apparent for some time. Bearing in mind the extent ofthese revisions, it was felt appropriate to expand the method of site testing into a “stand-alone“ document. Thiswould enable the velocity area methods to be fully detailed for all commonly encountered airway cross-sections. Itwould also
46、 allow the addition of descriptive annexes covering the selection of suitable measuring stations andinstrument calibration.In accordance with recent International agreements, it will be noted that fan pressure is now defined as thedifference between stagnation pressure at the fan inlet and outlet. S
47、tagnation pressure is the absolute pressurewhich would be measured at a point in a flowing gas if it were brought to rest isentropically. For Mach numbers lessthan 0,2 the gauge stagnation pressure is within 0,6 % of the total pressure.Less emphasis is placed on the use of “fan static pressure“ as t
48、his is a conventional quantity only. It is to beanticipated that its use will cease with time. All fluid losses are essentially losses in stagnation pressure and thishas been reflected in the definitions now specified.It should be recognized that the performance of a fan measured under site conditions will not necessarily be thesame as that determined from tests using standardized airways. The reasons for such differences are not only dueto the inherently lower accuracy of a site test, but also due to the so-called “system effect factor
