Wood & Copper Thermal Conductivity Apparatus

Consists of a cylindrical copper rod about 300 mm long & 25 mm diameter with its one end surrounded by a steam jacket for heating it from a boiler & the other end is kept cool by a system of water flowing through a spiral tube soldered to that end. Through two sockets, two thermometers are inserted in the rods for finding the temperature at two points. Two more thermometers are inserted in the other end which is kept cool by the stream of water. Through this apparatus, the difference of temperature between the inflowing & outflowing water is determined. Fitted in teak wood case, packed with felt with removable front; with thermometers.
