TecQuipment\u2019s Forced Convection Heat Transfer apparatus allows students to examine the theory and associated formulae related to forced convection in pipes<\/span><\/li>\n<li><span class=\"fontstyle0\">It is a frame holding a motor-driven fan, piping and<br \/>\ninstrumentation panel<\/span><\/li>\n<li><span class=\"fontstyle0\">The fan runs at a constant speed and draws air through a control valve. The air then moves into a u-shaped pipe. An orifice plate in the pipe connects to a manometer on the instrumentation panel to measure the airflow rate. A larger manometer on the instrument panel measures the fan pressure drop.<\/span><\/li>\n<li><span class=\"fontstyle0\">The u-shaped pipe connects to a smaller diameter insulated and electrically heated copper \u2018test pipe\u2019.<\/span><\/li>\n<li><span class=\"fontstyle0\">Students control the power input to the test pipe heater using a variable transformer, while noting the power using instrumentation on the panel. The test pipe discharges to atmosphere.<\/span><\/li>\n<li><span class=\"fontstyle0\">Pressure tappings each end of the test pipe connect to a manometer on the instrument panel to measure test length pressure drop.<\/span><\/li>\n<li><span class=\"fontstyle0\">A thermometer measures the air temperature at the inlet to the test pipe<\/span><\/li>\n<li><span class=\"fontstyle0\">Further thermocouples measure temperature at various points within the test pipe insulation<\/span><\/li>\n<\/ul>\n<p><em><span style=\"text-decoration: underline;\">Learning Outcomes:<\/span><\/em><\/p>\n<ul>\n<li>\u00a0<span class=\"fontstyle0\">Derivation of the value of Nusselt number (<\/span><span class=\"fontstyle2\">Nu<\/span><span class=\"fontstyle0\">) and comparison with empirical formula<\/span><\/li>\n<li><span class=\"fontstyle0\">Calculation of the local heat transfer coefficient (<\/span><span class=\"fontstyle2\">h<\/span><span class=\"fontstyle0\">)<\/span><\/li>\n<li><span class=\"fontstyle0\">Determination of the Stanton number (<\/span><span class=\"fontstyle2\">St<\/span><span class=\"fontstyle0\">)<\/span><\/li>\n<li><span class=\"fontstyle0\">Calculation of the friction factor (<\/span><span class=\"fontstyle2\">f<\/span><span class=\"fontstyle0\">) and comparison with experimental value<\/span><\/li>\n<li><span class=\"fontstyle0\">Determination of the validity of the Reynolds analogy for air<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Product Code: TD1<\/p>\n","protected":false},"featured_media":3135,"template":"","meta":[],"product_cat":[31,884],"product_tag":[],"_links":{"self":[{"href":"https:\/\/dbm.com.vn\/en\/wp-json\/wp\/v2\/product\/3496"}],"collection":[{"href":"https:\/\/dbm.com.vn\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/dbm.com.vn\/en\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/dbm.com.vn\/en\/wp-json\/wp\/v2\/media\/3135"}],"wp:attachment":[{"href":"https:\/\/dbm.com.vn\/en\/wp-json\/wp\/v2\/media?parent=3496"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/dbm.com.vn\/en\/wp-json\/wp\/v2\/product_cat?post=3496"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/dbm.com.vn\/en\/wp-json\/wp\/v2\/product_tag?post=3496"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
