DESCRIPTION:
The setup consists of a heater sandwiched between two sets of slabs. Three types of slabs are provided on either sides of heater, which forms a composite structure. A small hand press frame is provided to ensure the perfect contact between the slabs. A variac is provided for varying the input to the heater. Digital Voltmeter and Digital Ammeter display the heat input. Heat produced by heater flows axially on both the sides. Temperature Sensors are embedded at the interfaces of slabs to determine the temperature gradient. The experiment can be conducted at various values of heat input and calculation can be made accordingly.
EXPERIMENTATION:
- To determine total thermal resistance and thermal conductivity of composite wall.
- To plot temperature gradient along composite wall.
UTILITIES REQUIRED :
- Electricity Supply: 1 Phase, 220 V AC, 2 Amp.
- Table for set-up support.
