Q3. (20 marks) A solid cylinder of radius ri = 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 Pı? 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/P,?
