CRITICAL RADIUS OF INSULATING MATERIAL

RANGE OF EXPERIMENTS TO BE CARRIED OUT :
1. To determine thermal resistance & critical radius ofinsulating material.
2. The experiments can be conducted at various values of input &calculation can be made accordingly.
TECHNICAL DESCRIPTION :
The apparatus consists of one metal cylinder in which heater is fitted . The insulating material (asbestos belt) as lagging material is covered around the cylinder. Again the total assembly is insulated by glass wool & aluminum foil. The heat supplied to inner cylinder through heating coil by using a by a Autotransformer & is measured by Voltmeter & Ammeter.
Thermocouples are used to measure the temperatures, thermocouples 1 to 5 are fixed on metal cylinder and on the external side of insulating material.
DIMENSIONS AND WEIGHT :
