Viking 589a k factor formula sheet metal

You will note a 589a strong correlation between the nominal sprinkler orifice size and the published K factors. Microsoft 589a Word - Sheet metal calculations. Viking 589a k factor formula sheet metal. BA = [ sheet A x ( π/ 180) ( factor r + ( K viking x T) ) ]. You will notice that he smaller the sprinkler orifice size, the smaller the k- factor. sheet for any given sprinkler device. 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 589a by. It really all formula depends on what tooling is used viking to produce the sheet metal part and of course what material is being used. Sheet metal bend allowance calculator - formula & step by step 589a viking calculation to find the flat pattern metal length formula when a bend is dimensioned either from the centre of radius formula a tangent point of radius the outside tangent point of the radius on an acute angle bend.

A sample data sheet is shown in figure 3 and a representative list of K factor values is shown in table 1. doc Author: Ferlicius Ong Created viking Date: 6/ 1/ 15: 52: 36.

Sheet factor

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. The Viking Standard Response High Challenge® Upright Control Mode Specific Application. Technical Data Sheet.

viking 589a k factor formula sheet metal

The formula above is theoretical and once we take into account the effects of friction, turbulence and 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 reducing its complexity to a single constant " k". Though in more than 40 years of doing precision sheet metal work I have never specified or seen specified a K Factor on a print. Reference was made to a bend allowance used in calculating a flat pattern that was placed on a print in some cases on some ProE files from a major mailing equipment manufacturer.
