Project Overview
Project Name: Chem E Lab Equipment
Project Number: P13621
Project Family: ME and ChE Lab Hardware
Start Term: 2012-1
End Term: 2012-3
Mission Statement: To provide students with the
ability to observe conductive heat transfer and the
ability to measure the thermal conductivity of a
material.
Project Background/ Problem Statement:
The transfer of heat through a material in any
state is the process of heat transfer. Conductive
heat transfer through a solid has been done for
years in industry to heat or cool materials. The
materials ability to transfer heat is a measurable
quantity called thermal conductivity. Scientists
have an in-depth understanding of this material
property and have published data for various
materials. The chemical engineering department
is creating a laboratory experiment for observing
conductive heat transfer and measuring thermal
conductivity of multiple materials. This will
yield experimental results comparable to the
current published data.
Objectives/ Scope:
1. Develop apparatus for students to observe
conductive heat transfer and measure thermal
conductivities of various samples
2. Ability for students to compare experimental
results to published thermal conductivities
3. Obtain data from manual measurement and
DAQs
4. Visually demonstrate conductive heat transfer
5. Steady state heat transfer conditions
preferable; transient heat transfer conditions
optional.
Deliverables:
1. Conductive Heat Transfer Apparatus
2. Documentation to reproduce apparatus
3. Final Wiring Schematic
4. 3D modeling prints
5. Manufacturing spec sheets
6. Assembly instructions
Project Team:
Tatiana Stein (ChemE) – Team Facilitator
Rushil Rane (ISE) – Lead Engineer
Shayne Barry (ME) – Procurement
Jordan Hill (EE)
Piotr Radziszowski (ME)
Meka Iheme (ChemE)
Shannon McCormick (ChemE) – Project
Manager
Guide, customer & other attendees:
Neal Eckhaus – Guide
Steve Possanza – Guide
Karuna Koppula – Customer
Chinmay Patil – Field Expert
Expected Project Benefits: Students fully understand fundamental conductive
heat transfer concepts through observation and
experimentation. They will compare experimental
data with published thermal conductivities. Use
apparatus for demonstrations to students in other
engineering departments.
Assumptions:
To keep analysis simple for laboratory students, the
team must assume 1D steady state heat conduction
and the team must neglect losses.
Issues & Risks:
Successful integration of mechanical and
electrical subsystems
Proper documentation to quickly get back on
track in the spring
Ensuring simplicity for teaching students

Figure 10: Pugh Matrix for Thermal Insulation. Result: Fiber glass because of its low thermal conductivity, price, and
robustness.
Figure 11: Pugh Matrix for Providing a Heat Source. Result: Vertical heat plate is the best because of its price, ability
to allow for manual data collection and accurate provision of electrical heat flux.

Figure 12: Pugh Matrix for Recording Sample Dimensions. Result: Calipers and stopwatches because they are
relatively cheap, perform the most accurate measurements and can be quickly reset.
Figure 13: Pugh Matrix for Sample Holding. Results: Meter Bar + Heat sink offer the best options of cost and
insulation to prevent heat losses to sample holding.
Figure 14: Pugh Matrix for Temperature Acquisition. Results: Thermocouples because they have the best option for
bare surface area required and will yield the most accurate results.

Figure 15: Pugh Matrix for Temperature Display. Results: LED Readout and thermal crayon resulted as the best
concept for temperature display because of their safety, temperature range and relatively low cost.
