The shroud is open at the front and the inside surface is light coloured. This allows the students to see the flow clearly.<\/li>\n<li>Water enters a constant head tank (reservoir) above the test tube and passes through a diffuser and stilling bed. It then passes through a specially shaped bell-mouth into the test tube. This arrangement ensures a steady, uniform flow at entry to the test tube.<\/li>\n<li>A thermometer measures the temperature in the constant head reservoir.<\/li>\n<li>A fixed overflow pipe in the reservoir connects to a suitable drain. At the bottom of the test pipe is a valve which controls the flow rate through the pipe, without disturbing the flow.<\/li>\n<li>Students collect a known quantity of water in a measured time to find the flow rate. Included is a measuring cylinder.<\/li>\n<li>To see the pattern of flow in the pipe, students use a dye injector (included). They use it to inject a fine filament of dye into the top of the tube. The dye injector is a dye reservoir connected to a fine hypodermic tube.<\/li>\n<li>The base of the apparatus has adjustable feet for levelling prior to use (included is a levelling device).<\/li>\n<li>The optional Heater Module (H215a) is a separate free-standing unit. It connects to the water supply line to heat the water, varying its temperature and viscosity.<\/li>\n<li>Controls on the module vary the electrical heat input and the flow rate, to give steady conditions over a range of temperatures.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Product Code: H215<\/p>\n","protected":false},"featured_media":5611,"template":"","meta":[],"product_cat":[29,31,890],"product_tag":[],"_links":{"self":[{"href":"https:\/\/dbm.com.vn\/en\/wp-json\/wp\/v2\/product\/5614"}],"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\/5611"}],"wp:attachment":[{"href":"https:\/\/dbm.com.vn\/en\/wp-json\/wp\/v2\/media?parent=5614"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/dbm.com.vn\/en\/wp-json\/wp\/v2\/product_cat?post=5614"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/dbm.com.vn\/en\/wp-json\/wp\/v2\/product_tag?post=5614"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
