Sheet Microsoft Word - Sheet 589a metal calculations. Sheet metal bend metal allowance calculator - formula & step by step calculation to find the flat pattern length formula when a bend is dimensioned either viking from the centre of radius a tangent point of radius the outside sheet tangent point of the radius on an acute angle bend. doc Author: Ferlicius Ong Created Date: factor 6/ 1/ 15: 52: 36. It really all depends on what tooling is used to factor produce 589a the sheet metal part and of course what material is being formula factor used. Reference viking viking was made to a viking bend allowance used in calculating a flat pattern that was placed on a print in some cases formula on some ProE files from a major mailing equipment manufacturer. Though in more than 40 years of doing precision sheet metal 589a work I k have never specified or seen specified a K Factor on a print. BA = [ A formula factor x ( π/ 180) ( r + ( K x T) ) ]. The Viking Standard Response High Challenge® Upright Control Mode Specific 589a Application.
You will notice 589a that he smaller the sprinkler orifice size, the smaller the k- factor. The information on sheet the web site above helped me greatly achieve a somewhat accurate viking K- Factor until I was finally given our companies K- Factor Chart that we go by. Viking 589a k factor formula sheet metal. Technical Data Sheet.
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. 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 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".
viking 589a k factor formula sheet metal
There are standard charts available with sheet metal design handbook for calculating K factor ( ideally it should be 0. But the most accurate way to find out K factor is reverse engineering of a small but same sheet metal sample piece. sheet for any given sprinkler device.
