THERMAL CONDUCTIVITY OF LIQUIDS BY GUARDED HOT PLATE

/in /by

RANGE OF EXPERIMENTS TO BE CARRIED OUT :
1. To determine the thermal conductivityOf Liquid.
2. The experiments can be conducted at various values of input
& calculation can be made accordingly.
.
TECHNICAL DESCRIPTION :
The heater plate is surrounded by a heating ring for stabilizing the temperature of the primary heater & prevent heat loss readily around its edges. The primary & guard heater are made up of mica sheets in which is wound closely spaced Nichrome wire & packed with upper & lower mica sheets. These heaters together form flat with upper & lower copper plate & rings from the heater plate assembly.
Two thermocouples are used to measure the hot face temperature at the upper & lower central heater assembly copper plates. Two more thermocouples are used to check balance in both the heater inputs.

Specimens are held between the heater & cooling unit on each side of the apparatus.
Thermocouples No. 5 & 6 measure the temperature of the upper cooling plate &
lower cooling plate respectively.
The heater plate assembly together with cooling plates & specimen hold in position by
3 vertical stands & nuts on a base plate
The cooling chamber is a composite assembly of grooved aluminum casting&
aluminum cover with entry & exit adapters for water inlet & outlet.
