Flow Boiling Demonstration Apparatus Manufacturer,Supplier and Exporter in India
Product Code : SCL-CELE-13921
Indian Lab Suppliers supplies the Flow Boiling Demonstration Apparatus (Product ID: 13921) as part of its Civil Engineering Lab Equipment range. It shows the flow patterns of boiling inside a heated glass pipe.
Quick Answer
Hot water in the outer jacket of a double-wall glass pipe evaporates a non-toxic liquid (boiling point 40 to 50 °C) flowing through the inner pipe. A water-jet vacuum pump lowers the pressure so evaporation happens at low temperature. Students watch the change from single-phase liquid through bubbly, slug, annular, film and mist flow to single-phase vapour, and see how flow rate, temperature and pressure affect it.
