Q3. (20 marks) A solid cylinder of radius r1 = 6 cm, length h1 =
7.5 cm, emissivity 0.75, and temperature 50°C is suspended in an
environment of temperature 30°C.
a) What is the cylinder’s net thermal radiation transfer rate
P1?
b) If the cylinder is stretched until its radius is r2 = 1.5 cm,
its net thermal radiation transfer rate becomes P2. What is the
ratio P2 /P1?
