Question
Two large aluminum plates k 240 W/m.K each 1 cm thick,
with 10 𝜇m surface roughness are placed in contact under 10 5
N/m^2 pressure in air as shown in Fig 7 The temperatures at the
outside surfaces are 395 C and 405 C Given that contact
resistance is 2 75 x 10 4 m 2 K/W, calculate
a.Heat flux
b.Interface temperature, T 3
