Viking 589a k factor formula sheet metal

Doc Author: Ferlicius Ong Created Date: 6/ 1/ 15: 52: 36. A sample data sheet is shown formula in figure 3 and a representative metal list of K factor values is shown in table 1. You will note a strong correlation metal 589a between the nominal sprinkler orifice size and the published K factors. The formula above is theoretical turbulence , once 589a we take into account the effects of friction the contraction of the water stream the formula can be simplified to what we know as the k- factor formula for fire protection system by formula reducing its viking complexity to a single constant viking " k". Viking 589a k factor formula sheet metal. But the most accurate way to find out 589a K factor is reverse engineering of a small but same sheet metal sample piece. viking Though in more than 40 years of doing precision sheet metal 589a work I have never specified or seen specified a K Factor on 589a a print. Reference was made to a bend allowance used in calculating viking a flat pattern that was placed on a print in some cases on some ProE files from a major mailing equipment manufacturer. sheet for any given sprinkler device.

Microsoft viking Word - Sheet metal calculations. You sheet will notice that he smaller the sprinkler orifice size, the smaller the k- factor.

The Viking Standard Response High Challenge® Upright Control Mode Specific Application. Technical Data Sheet. K- Factor in Flow Test Using Hazen- Williams Formula In Hazen- Williams formula, flow is proportional to pressure to 1. 85- th power, and thus K- factor is slightly different from that calculated by the above formula. The computer- aided design software you are using may employ a Y- factor instead of a k- factor when calculating for BA and the BD, enabling you to create a more precise flat pattern for your sheet metal part. It really all depends on what tooling is used to produce the sheet metal part and of course what material is being used.

The information on the web site above helped me greatly achieve a somewhat accurate K- Factor until I was finally given our companies K- Factor Chart that we go by. Sheet metal bend allowance calculator - formula & step by step calculation to find the flat pattern length when a bend is dimensioned either from the centre of radius or a tangent point of radius or the outside tangent point of the radius on an acute angle bend. BA = [ A x ( π/ 180) ( r + ( K x T) ) ].
