Connectors of one of the manufacturers generally available on the Polish market<br \/>\nwere proposed in the analysis. The paper is limited to three typical and most common sizes. The comparative<br \/>\nanalysis includes coefficients obtained by direct laboratory measurements, using CFD modeling, analytically using<br \/>\nstandard 1D formulas and values declared by the manufacturer. Measurements and 3D modeling have shown that<br \/>\nthe value of the loss factor can be presented as a non-increasing function depending on the average velocity behind<br \/>\nthe connectors. Significant differences were found between the values of the local loss factors determined in different<br \/>\nways. Taking into account in the calculations the values significantly deviating from the real one may increase or<br \/>\ndecrease of the flow. Reducing the flow may result in not achieving design parameters. Overdesigning an installation<br \/>\nmay result in not reaching design parameters, which is created by assuming too large diameters of the conductors,<br \/>\nwhich is ultimately associated with higher material costs. The results presented here can be used as a source of<br \/>\ndesign parameters for designers of pressure installations.<\/p>\n","protected":false},"featured_media":0,"parent":0,"menu_order":0,"template":"","meta":[],"tags":[995,2983,2985,2338,2984],"tematyka":[1143],"class_list":["post-17895","artykul","type-artykul","status-publish","hentry","tag-cfd","tag-connector","tag-head-loss-coefficient-in-pipes","tag-local-loss-coefficient","tag-press-system","tematyka-cold-and-hot-water-and-heating-systems","has-post-title","has-post-date","has-post-category","has-post-tag","has-post-comment","has-post-author",""],"ptb_metabox":{"ptb_artykul_text_1":["ROBERT MA\u0143KO"],"ptb_artykul_text_2":"DOI 10.36119\/15.2022.4.2","ptb_artykul_numer_miesi_cznika":"04\/2022 Instal p. 22-26","ptb_artykul_info_autor":"Dr in\u017c.
