Project OverviewMission Statement: To provide students with the ability to observe conductive heat transfer and the ability to measure the thermal conductivity of a material.

Background:

• A material’s ability to transfer heat is a measurable quantity

• RIT ChemE department would like to procure lab equipment that would demonstrate heat transfer such that students may be able to calculate thermal conductivity

• Experimental results would be comparable to published data

Objectives• Develop apparatus to observe conductive heat transfer• Enable students to compare experimental and published

values for thermal conductivities• Obtain experimental data from manual and DAQ

measurements• Visually demonstrate conductive heat transfer• Demonstrate steady state heat transfer (Transient heat

transfer is optional)
