Double pipe heat exchanger (concentric)

The purpose of this experiment is to calculate the amount of transferred heat, the logarithmic temperature and the overall heat transfer coefficient, the comparison of parallel flow and non-symmetric flow in a heat exchanger.
The process of heat exchange between two fluids of different temperatures separated by a solid wall occurs in many engineering applications. The device used for this exchange is called a heat exchanger.
The hot water unit includes a tank and an electric heater with a power of 2.5 kW that heats the water to the desired temperature. A thermostat is used to control the temperature of the incoming hot water. The inlet hot water temperature can be adjusted by the display screen. The tank must be filled with distilled water to prevent sedimentation of the pipes.
