Q3. (20 marks) A solid cylinder of radius rı = 2.5 cm, length h1 = 5.0 cm, emissivity 0.85, and temperature 100°C is suspended in an environment of temperature 50°C. a) What is the cylinder's net thermal radiation transfer rate P.? b) If the cylinder is stretched until its radius is n2 =0.5 cm, its net thermal radiation transfer rate becomes P2. What is the ratio P2/P?
