Product Description

At particular radius of insulation over a cylinder, loss of heat is maximum. The ‘Swarg Systems & Instruments’ unit consists of G.I. pipes provided with plaster of paris insulation of different thickness on outside surface. Four pipes are provided with heater inside having input control. Input to heaters is measured by common voltmeter and ammeter. By controlling input to heaters, it is shown that critical radius of insulation is ratio of thermal conductivity and outside heat transfer co-efficient.
