The curves are plotted for a range of ratios of specific heat capacities from 1 to 1.67 and for Mach numbers to unity. The equations can be applied to all Mach numbers provided no dissociation occurs. The conditions covered are 1. at a point in the flow, the ratio of static\/total temperature, of static\/total pressure, and of velocity\/speed of sound in the gas brought isentropically to rest; 2. at a point in the flow, the ratios of kinetic\/total pressure and of dynamic\/kinetic pressure; 3. for the expansion of a gas through a nozzle with sonic flow at the throat, the ratio as a function of Mach number of the pressure, temperature and area at any point in the flow to the pressure, temperature and area respectively at the throat; 4. in the expansion from a reservoir, the ratio of density, temperature and velocity to the corresponding reservoir conditions as a function of pressure ratio and 5. three mass flow functions involving total pressure and temperature, total temperature but static pressure, and static pressure and temperature.\n\t<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>One-Dimensional Compressible Gas Flow in Ducts<\/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>28<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":557983,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[2675],"product_tag":[],"class_list":{"0":"post-557971","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\/557971","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\/557983"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=557971"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=557971"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=557971"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
