Product Description

The ‘Swarg Systems & Instruments’ apparatus consists of a pin type fin heated by a band heater at one end. A centrifugal blower draws air over the fin. Thermocouples are attached along the length of fin to note down the longitudinal temperature gradient. Heat input to the fin is measured from electrical input to the fin. Air flow is measured by an orifice and water manometer. Thus the students can conduct the experiments in natural and forced convection and at various airflow rates, various heat inputs and with fins of different materials.
