Heat Transfer Through Composite Wall for engineering schools

Heat Transfer Through Composite Wall Apparatus Manufacturer, Supplier and Exporter – Designed for engineering and heat transfer laboratories, this apparatus is used to study heat conduction through a composite wall and determine thermal resistance and thermal conductivity of different materials. The setup consists of a centrally mounted heater with interchangeable slabs on both sides, allowing students to observe temperature distribution and heat flow under steady-state conditions.

Experiments:

• Determination of total thermal resistance and thermal conductivity of a composite wall

• Plotting the temperature gradient across a composite wall

Utilities Required:

• Electric supply: 220 V AC, Single Phase, 2 Amp

• Laboratory table for mounting the setup

Technical Specifications:

• Symmetrical slab assembly on both sides of the heater

• Slab materials:
