The apparatus consists of two small test cylinders of same size but different material. Each cylinder is fitted with a temperature sensor in the centre to observe the temperature of cylinder when is under study. Any one of them is heated by a constant temperature water bath, till steady state is reached. During heating, temperature of the cylinder is a function of time and hence, heating of cylinder is under unsteady state heat transfer. A digital temperature indicator is provided. The hot water bath is provided with a heater and is controlled by digital temperature controller. A fixed speed agitator is also provided to maintain the constant bath temperature.

•An ENGLISH instruction manual consisting of experimental procedures, block diagram etc. will be provided along with the Apparatus.

•The whole set-up is well designed and arranged on a rigid structure painted with industrial PU Paint.

Experimentation/Learning Objectives
