These data include measurements and numerical<br \/>\npredictions of the flow field and pressure distribution over the<br \/>\norifice test pipe, pressure drops across the orifice plate, and<br \/>\npressure loss and discharge coefficients data. Although a<br \/>\nconsiderable part of the data reviewed is from measurements in<br \/>\norifice flow-meters and in support of their international<br \/>\nstandards, the data reviewed here are beyond these standards.<\/p>\n<p>The consistency of the data and the effects of non-standard<br \/>\nflow, operation and installation conditions are discussed. The main<br \/>\nemphasis of this Technical Note is on data for: (1) circular,<br \/>\nconcentric orifices in circular pipes, (2) ducts with identical<br \/>\ndownstream and upstream cross-sectional areas, (3) laminar,<br \/>\ntransitional and turbulent flow regimes, (4) fully-developed,<br \/>\nswirl-free, steady flow conditions with no-cross flow upstream and<br \/>\ndownstream of the orifice plate, and (5) single-phase, Newtonian<br \/>\nliquids and gases in incompressible flow. However, a brief review<br \/>\non the data for cooling holes, annular and non-circular orifices,<br \/>\nand perforated plates is also presented.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Incompressible Flow Through Orifice Plates &#8211; a Review of the Data in the Literature<\/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>2012-02<\/td>\n<td>125<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":559946,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[2675],"product_tag":[],"class_list":{"0":"post-559938","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\/559938","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\/559946"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=559938"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=559938"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=559938"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
