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 temperature 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 ≤ φ ≤ 0.08.
