Product Description

The ‘Swarg Systems & Instruments’ apparatus consists of a mica heater sandwiched between two identical composite slabs on either sides. Heat produced by heater flows axially on both the sides. Thermocouples are introduced at the interfaces of slabs to determine the temperature gradient. Water-cooled heat sinks are provided at the end of slabs. so that steady state heat transfer condition is achieved earlier. Thus students can determine the thermal resistance of slab at various heat inputs and different configurations.
