Unsteady State Heat Transfer Unit

Model No. HTL0015

The apparatus consists of a small test cylinder. The cylinder is heated by a constant temperature water bath, till steady state is reached. During heating, temperature of the cylinder is function of time and hence, heating of cylinder is unsteady state heat transfer. The temperature of cylinder is measured with the help of temperature sensor inserted in the center. The hot water bath is provided with a heater and is controlled by digital temperature controller. An agitator is also provided to maintain the constant temperature.

Experiments

• To calculate the Biot number, Fourier number and to calculate the heat transfer coefficient
• To plot Heisler Chart for the given sa1l1pleof cylindrical solid

Utilities Required

• Electricity Supply: 1 Phase, 220 V AC, I kW.
• Bench area of 1.5m x 1.5m
