They also need to know how this force influences the rate of momentum flow in the jet.<\/li>\n<li>This product shows students the force produced by a jet of water as it strikes a flat plate, a hemispherical cup, a 120-degree conical plate or a 30-degree angled plate. They can then compare this to the momentum flow rate in the jet.<\/li>\n<li>TecQuipment\u2019s Digital Hydraulic Bench (H1F, available separately)* provides the water source for experiments. The Impact of a Jet consists of a transparent cylinder containing a vertically tapered nozzle and a test plate. The cylinder is on legs and mounts on the top of the hydraulic bench.<\/li>\n<li>The nozzle, supplied by the hydraulic bench, produces a high-velocity jet of water which hits the test plate. The test plate connects to a weigh beam assembly with jockey weight which measures the jet force.<\/li>\n<li>A drain tube in the base of the cylinder directs water back into the hydraulic bench, allowing accurate flow rate measurement.<\/li>\n<li>All test plates are all easily interchangeable, taking only a few seconds and needing no tools. To perform experiments, students level the apparatus and zero the weigh beam assembly. They set the flow from the hydraulic bench to maximum, and measure the jet force. They reduce the flow from the hydraulic bench in several increments. At each increment they record the force of the<br \/>\njet on the plate and the flow rate. They then repeat the experiments for different test plates. Students compare their experimental results to those calculated from theory, working out charts of rate of force on plate and rate of delivery of momentum.<\/li>\n<\/ul>\n<p><em><span style=\"text-decoration: underline;\">Learning Outcomes:<\/span><\/em><\/p>\n<ul>\n<li>Measurement of the impact force and comparison with momentum change of four different plates:\n<ul>\n<li>Flat plate<\/li>\n<li>Hemispherical plate<\/li>\n<li>Inclined flat plate<\/li>\n<li>120-degree conical plate<\/li>\n<li>30-degree angled plate<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Product Code: H8<\/p>\n","protected":false},"featured_media":5284,"template":"","meta":[],"product_cat":[29,31,890],"product_tag":[],"_links":{"self":[{"href":"https:\/\/dbm.com.vn\/en\/wp-json\/wp\/v2\/product\/5287"}],"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\/5284"}],"wp:attachment":[{"href":"https:\/\/dbm.com.vn\/en\/wp-json\/wp\/v2\/media?parent=5287"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/dbm.com.vn\/en\/wp-json\/wp\/v2\/product_cat?post=5287"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/dbm.com.vn\/en\/wp-json\/wp\/v2\/product_tag?post=5287"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
