Thermal Conductivity of Liquids

Thermal Conductivity of Liquids The apparatus is designed to determine thermal conductivity of different liquids. The apparatus consists of a heater. The heater heats a thin layer of liquid. A cooling plate removes heat through liquid layer, ensuring unidirectional heat flow. Temperature is measured across the liquid layer and complete assembly is properly insulated. A properarrangement for changing the liquids is provided. The whole assembly is kept in a chamber.  EXPERIMENTATION:  Ø  Determination of thermal conductivity of liquid. Ø  Study of variation of thermal conductivity of liquid with temperature.   UTILITIES REQUIRED :   Ø  Water supply 5 lit/min (approx.) Ø  Drain. Ø  Electricity Supply: 1 Phase, 220 V AC, 2 Amp.
