2.21 Use IHT to perform the following tasks.
(a) Graph the thermal conductivity of pure copper,
2024 aluminum, and AISI 302 stainless steel over
the temperature range 300 T 600 K. Include
all data on a single graph, and comment on the
trends you observe.
(b) Graph the thermal conductivity of helium and air
over the temperature range 300 T 800 K.
Include the data on a single graph, and comment on
the trends you observe.
(c) Graph the kinematic viscosity of engine oil,
ethylene glycol, and liquid water over the tempera-
ture range 300 T 360 K. Include all data on
a single graph, and comment on the trends you
observe.
(d) Graph the thermal conductivity of a water-Al2O3
nanofluid at T 300 K over the volume fraction
range 0 0.08. See Example 2.2.
