Project Overview
Mission 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

X = Ideal Insulation Thickness (m)
K = Thermal Conductivity (W/mK)
A = Area of Sample (m2)
T2 = Outside Temperature (K or C)
T1 = Sample Temperature (K or C)
Q = Power in (W)
It is infeasible to use
deterministic methods due to the
many non-converging values of X
resulting from combinations of Q
and T1 . T2 values also change
along the length of the sample,
adding to the complexity of a
deterministic model.

K – Held Constant (0.2 W/mK)
A – Held Constant (0.0079 m2)
T2 – Held Constant (20 C)
-Q and T1 are varied
simultaneously
-Generate large data set and
use stochastic methods to
determine best insulation

Conclusions from Lab
•Aluminum graph was more linear than the
copper graph
•Aluminum sample was longer than
the copper sample  the longer the
sample size, the better the accuracy
that was achieved
