A reference pressure drop that is a function of gauze porosity is first predicted. An empirical factor corrects that reference pressure drop for the effect of Reynolds number less than 2000 (based on wire diameter); that factor is unity for higher Reynolds numbers. Another empirical factor that is a function of porosity and Mach number corrects the pressure drop in gas flow for compressibility; two forms are given, one of which yields the static pressure drop while the other yields the total pressure drop across the gauze. The data can be applied to square- or rectangular-mesh gauzes. Sources are listed of information on the effect of supersonic flow, choking and inclining the gauze to the flow.\n\t<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Pressure Drop in Ducts Across Round-Wire Gauzes Normal to the Flow<\/b><\/p>\n<table style=\"width: 100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td>Published By<\/td>\n<td>Publication Date<\/td>\n<td>Number of Pages<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pdfstandards.shop\/product-category\/publishers\/esdu\/\"><b>ESDU<\/b><\/a><\/td>\n<td>2007-03<\/td>\n<td>19<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":557877,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[2675],"product_tag":[],"class_list":{"0":"post-557867","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-esdu","8":"first","9":"instock","10":"sold-individually","11":"shipping-taxable","12":"purchasable","13":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/557867","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media\/557877"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=557867"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=557867"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=557867"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
