Thermal Conductivity of Liquids

Thermal Conductivity of Liquids Description and Specifications for Lab Tenders

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.
