4B30.55 - Heat Transfer - Copper Coils
Code Number:
References:
4B30.55
Demo Title:
Heat Transfer - Copper Coils
Condition:
Good
Principle:
Conductivity
Area of Study:
Heat & Fluids
Equipment:
Copper coils and tubing, Digital Thermometers (2 or 4), 1000 ml Beakers (2), Beer, Colored Water, Small wooden stand.
Procedure:
Foaming of the beer may hinder this demo. To get around this it is advisable to let the beer stand open at room temperature 24 hrs prior to demonstration. Also at this time place the colored water in a refrigerator for cooling. The larger the difference in temperature between the two liquids the better this demonstration will work. Therefore, before demonstrating, the beer is heated to almost boiling, stirring vigorously several times to release Carbon Dioxide . With the warm beer and the chilled water the demonstration is started and continued by gravity siphon. The initial temperatures of the two liquids must be taken and recorded before starting. Transfer the probes to the receiving beakers and record the temperature of the liquids after transfer. Heat transfer efficiency should be 90% to 95%.
