The Agitated Vessel (Jacket & Coil) trainer is designed to study heat transfer through agitation, jacket, and coil systems. It demonstrates the effects of stirring speed and temperature difference on heat transfer efficiency. The unit includes a stainless-steel vessel with jacket and coil arrangements, thermocouples, and a digital indicator for accurate readings. Students can perform experiments on overall heat-transfer coefficients and study different operating parameters. Ideal for engineering colleges, polytechnic institutes, and ITIs, this apparatus combines durability, safety, and practical clarity in heat-transfer studies.
