Description

It consists of a copper rod with a diameter of 300 x 25mm (Length x diameter). One end is covered with a steam jacket to heat it from a boiler, and the other is kept cool by a system of water flowing through a spiral tube soldered to that end. Two thermometers are inserted into the rod through two sockets to measure temperatures at two locations. Two additional thermometers are inserted into the opposite end, which is cooled by a stream of water that flows through a spiral tube soldered to that end. The purpose of this procedure is to determine the temperature difference between the metals flowing in and out of the device. Packed in a wooden case. Supplied without thermometer.

Working Principle: (NOT MEANT FOR CATALOGUE)

• The rod is heated at one end using steam and cooled at the other end using running water.
• The steady-state temperatures at both ends are measured.
• Using heat flow equations, thermal conductivity kkk is calculated:

Q=k?A?(T1?T2)LQ = frac{k cdot A cdot (T_1 – T_2)}{L}Q=Lk?A?(T1??T2?)?
