Can you use Crane K for fitting sizes?Can you use Crane K for fitting sizes?you can see that if you use a K value the pressure drop is not influenced by the fitting size or the Reynolds number. When you use Crane K values the value is corrected (via the table on page A-26) for fitting size before you insert the value into the D-W equation, but many of the older references gave single K values for all fitting sizes.Crane 410 fittings - Pipelines, Piping and Fluid Mechanics crane pipe fitting k values africa Is laminar flow better than Crane K?Is laminar flow better than Crane K?If you are working with laminar flow it is much better to work with equivalent lengths than with fixed or even Crane K values.
