MEM311: Thermal and Fluid Science Laboratory Experiment 3: Heat Transfer from a Circular Cylinder 30 | P a g e D.PROCEDURE***Before operating the equipment, please understand that the heated cylinder will reach temperatures above 500°C. Serious skin burns will result if the equipment is mishandled. Please ask an instructor if you have any questions or concerns. Equipment Set-up Before proceeding with the exercise, ensure that the equipment has been prepared as follows: 1.Locate HT14 Combined Convection and Radiation accessory alongside the HT10X Heat Transfer Service Unit on a suitable bench. 2.Ensure that the horizontal cylinder is located at the top of the vertical metal duct with the T10 thermocouple attached. 3.Connect the thermocouple attached to the horizontal cylinder to socket T10 on the front of the service unit. 4.Connect the thermocouple located in the vertical duct to socket T9 on the service unit. 5.Set the voltage control potentiometer to minimum (counterclockwise) and the selector switch to MANUAL. 6.Connect the power lead from the heated cylinder on the HT14 to the socket marked O/P3 at the rear of the service unit. 7.Ensure that the service unit is connected to an electrical supply. Experimental Procedures You will perform 2 sets of experiments: one for naturalconvection, and another for forcedconvection. For the naturalconvection conditions, you will measure the steady state temperature achieved on the cylinder for 4 different heating voltages (7, 10, 13, and 16 volts). For the forcedconvection cases, you will measure the steady state temperature achieved on the cylinder for 5 different flow velocities (approximately equally spaced between 0 m/s and the maximum attainable by the device), all at a heating voltage of 10 volts.
