Model No. TD-8513 Experiment #1: Heat Conduction

Experiment #1: Heat Conduction

Set-up

1. On the power supply, turn the Function switch to SET MAX and set the voltage

limit to 8 V; this will prevent accidental overload during the experiment. Turn the

Function switch to constant DC mode ( ).

2. Use two banana patch cords to connect the power supply to the Heat Conduction

Apparatus. Connect the positive (+) terminal of the power supply to the red input

jack of the Heat Conduction Apparatus; connect the negative (−) terminal of the

power supply to the black input jack of the Heat Conduction Apparatus.

3. Use the included cable to connect the temperature port of the apparatus to the

multiport of the Temperature Array. Connect the Temperature Array to the

PASPORT interface. Connect the interface to a computer and start DataStudio.

4. Measure the distance between the two thermistors embedded in each bar; their

positions are marked by the white lines on the board.

5. Make a drawing showing the layout of the apparatus including the Peltier device,

the four bars, and the thermistors. Label each thermistor with the following des-

ignations:

T1 Wide Brass (far)

T2 Wide Brass (close)

T3 Narrow Brass (close)

T4 Narrow Brass (far)

T5 Aluminum (far)

T6 Aluminum (close)

T7 Stainless (close)

T8 Stainless (far)

A. Heat Conduction Race

Set-up

1. Set the switch to HEAT and place the insulators over the bars.

2. In DataStudio, set the sampling rate of the Temperature Array to 5 Hz. Set up a

graph display to show the temperatures measured by all four “far” thermistors

(T1, T4, T5, and T8).

3. Collect a test run of data to make sure that all four bars are all at room tempera-

ture. Delete the data.
